Cons: "I paid extra to sit in the front of the plane and the flight attendant kept an egregiously bright LED light on that shined in my face the entire 4+ hour trip. I was really tired and extremely upset that there was no curtain or anything to stop this light from shining directly at my seat."

Cons: "Three gate changes and then delays of ramp connecting to plane. It was ok"

Pros: "Seats were pretty comfortable as plane seats go. And overall the plane appeared very clean"
Cons: "Multiple delays, which is really nobody’s fault if it’s weather related but it causes multiple gate changes. We were traveling with an infant so we expected to get seated together, we got the same row but had an elderly person between us. We kindly asked if she would want to switch seats which she was fine with but who seats someone like that?! overall it wasn’t terrible but it felt like nobody has their stuff together and 5 hours were added on to our travel day"

Cons: "Left 5 hours late. Not notified til I left for airport. Sat on the plane almost 90 minutes before we took off. Flight was good"

Cons: "The flight was delayed for quite awhile. I had been traveling all day and I just wanted to go home. We also were not informed why it was delayed for so long."

Cons: "Tv’s were fickle and my other seat had no audio."

Pros: "The flight was on time, and we boarded quickly and promptly."
Cons: "They sat me next to the bathroom which I found really disgusting. It was hard to eat while listening to people endlessly flush the toilet. Disgusting."

Cons: "Just flying with no 3h delays."

Pros: "Crew was great."
Cons: "Everything was fine. It was a smooth trip to Denver."

Pros: "On point"
Cons: "Keep the good work"

Pros: "The crew was great. They let me go back to see if I could find my laptop that JFK TSA did not return."

Pros: "My seat was broken, so I couldn't recline, which made my lower back ache. The TV was fuzzy and several channels didn't work, and others would cut in and out"
Cons: "Took me asking twice where my coffee was. Flight attendant forgot."

Pros: "The JetBlue crew as always was friendly and helpful. Love the snacks. We like JetBlue far more than other airlines. This trip was partially due to a credit from a previous trip, which was cancelled due to medical issues. Getting a credit was very painless, and the agent was sooo courteous and helpful! Just a great airline!"
Cons: "Logan needs to be updated. The concourse is old, worn out, disorganized. Due to weather our flight was a bit late, but everyone kept us well-informed. A most pleasant surprise compared to a certain "Untidy" airline with cramped seats, lots of extra charges, late flights, and a crabby crew."

Pros: "The cabin crew came through to collect waste from the passengers and made an effort to separate recyclables from trash. Air travel generates too much waste so it's nice to see JetBlue making an effort to reduce waste."

Pros: "There was free internet in the flight! In addition to movies and what not."
Cons: "It only flies out of JFK, and it is a bit far for me"

Pros: "The leg room was great, and the trip was enjoyable."

Cons: "Unfortunately one of the monitors wasn’t working."

Cons: "No working internet or video"

Cons: "Plane was 3 1/2 hours late."

Pros: "Great selection of food and entertainment, nice service."
Cons: "We taxied for 40 minutes before taking off without getting any information about why we weren’t moving."

Pros: "The TV was nice"
Cons: "Some of the most uncomfortable seats both to and from Denver that I have ever sat in. Felt like sitting on a stone park bench. My back still aches 2 days later. It was a redeye, so I didn't much interact with the crew, but they seemed efficient and professional. They did not wake up during drink service, which was appreciated. Those planes suck!"

Pros: "They canceled the fly and left me in NY 3 days did not gave any reson for wy they cancel the flight and the didn’t help with hotel or noting cal"

Pros: "On time flights with punctual boarding and early arrival Polite flight attendants Pilots pointed out areas of interest during the flight Comfortable take off and landing Unlimited snacks and beverages, even on shorter flights Free entertainment, even on shorter flights"

Pros: "Leg room was good."
Cons: "The flight was delayed twice, then we had to sit on the plane for around 45 minutes before we could take off. I never seem to get in and out of JFK on JetBlue without some type of delay."

Cons: "No in flight ent or wifi"

Pros: "The seats are comfortable. Enjoyed the TV. JetBlue is our preferred airline. Haven't had a bad experience."
Cons: "The free snacks could be a lot healthier, i.e. apples, hummus,"

Pros: "We arrived earlier than expected and easy boarding."

Pros: "JetBlue did a good job, as usual."
Cons: "There was a screaming Infant in the seat next to me that continued to scream for the first hour and a half. I requested earplugs, and wore them under my 34 dB noise isolating earmuffs (which were made for use at a gun range). The screaming was still loud enough to give me the worst headache that I've had in 4 years. Once this baby stopped, the baby in the row behind me began to scream and the one across the isle from him/her joined in. I would happily rebook with JetBlue if there was an option to not be seated within 5 rows of a toddler."

Pros: "Leg room, comfort, travel time"
Cons: "Flight was late an hour, and the snacks were okay."

Pros: "Boarding from back of plane"
Cons: "Didn't get snack I asked for and what I got (popcorn chips) I didn't like. Also chair wouldn't recline"

Cons: "you never put my luggage on my flight, so I had no clothing for the day."

Cons: "Online check in refused to let me pick a seat even though the plane was not full. It then did not generate, or allow me to print at the airport, a boarding pass. When my connection arrived at 7pm I stood in line at the gate while the airline employee working completely ignored us for a solid 15 minutes waiting to get my boarding pass. the flight then said it was delayed with a departure time of 9:05 and we did not even start boarding until after 9pm."

Pros: "Boarding first from rear seats worked for me because that's where I was sitting. Worked also for people in rows before they were announced. Gate agent didn't care I guess. My row mates get credit for sharing my middle armrests. Seats are tight. Loved the free Direct TV. Perfect for longer flights. Chose no food"
Cons: "Boarding first from rear seats worked for me because that's where I was sitting. Worked also for people in rows before they were announced. Gate agent didn't care I guess. My row mates get credit for sharing my middle armrests. Seats are tight. Crew didn't enforce the 'upright & locked' in row ahead at landing"

Pros: "Even in regular couch seats I found the leg room to be good."
Cons: "Flight crew was efficient but not particularly friendly. Could smile more."

Cons: "Had to pay for snacks and blanket, which is ridiculous. Very disappointed."

Pros: "Nice flight attendants..."
Cons: "Very cold in cabin-"

Pros: "Jet Blue treats its customers like they are real people and not just stock to be moved. There is adequate legroom. Their personnel are friendly and competent. This alone puts them above most airlines."

Pros: "After a long day of flights and airports it was a nice way to end the trip. Comfortable seats and no frills with class"

Pros: "Everything was a wonderful experience with Jet Blue"

Pros: "Friendly crew"
Cons: "Not piling up people like sardines in a can."

Pros: "Food was good and plentiful."
Cons: "There was no way for us to reserve seats with extra leg room 48 hours before the flight. Had to sit in agony for a 9 hour flight because of height"

Cons: "You could have had my luggage arrive. Now I don’t know where it is"

Cons: "On time"

Pros: "Crew was amazing. Good movie selection. Pretty comfortable."
Cons: "Six hour delay. They gave us $20 Franc voucher for food but in the airport a latte is 7.50 so 20 did not even buy a bowl of soup."

Pros: "Crew was fantastic"
Cons: "Boarding was delayed by 30 minutes. May have been beyond the crew control."

Pros: "Bombardier C Series. Most leg room and comfort of any plane"

Pros: "Great. Very smooth and comfortable!"

Pros: "Excellent"

Pros: "The crew were helpful and polite"
Cons: "The boarding process was too long and chaotic in Zurich The seats are uncomfortably close together and there is not enough room to move at all. I would say for bigger size people, they mau even be unsafe. I have had high regards for Swiss airline until my recent trip. I will definitely look for other options for my future trips."

Pros: "The crew were great and boarding went very smoothly."
Cons: "After such a smooth boarding we found we had to sit on the tarmac for an hour because of congestion at Zurich."

Pros: "Customer service excellent even though I was in the economic class they made me feel first class!"

Pros: "Efficient, excellent staff and service, beautiful plane"
Cons: "There was a nearly impossible connection time in Zurich."

Pros: "Excellent service all around and great flight timing with delays and awaiting for transfer flights to land"
Cons: "I travel a least 5 times a year and Kayak is always my option."

Cons: "They canceled the flight and took me to another company with a stop in Turkey,it was a really bad and uncomfortable flight And I’m really disappointed!!!!!"

Cons: "Outdated plane."

Pros: "Seats were comfortable, food was ok."

Pros: "Crew was always ready to help. It was a very smooth flight."
Cons: "I wish we could start watching the movies earlier and wish there was more selection for good movies. Flight was delayed but we knew that. I prefer that it‘s safe."

Cons: "Boarding chaotic- no clear lines people pushing ahead which I am not used to- my handluggage was ok’ed at origin in US- was pulled aside in Zurich based on my “ ticket”- it was perfectly well suited and not oversized. In plane half of overhead compartments were filled with coats when told that these should go under seats. No consistency between announcements and behavior of crew."

Pros: "Courteous Service and excellent hospitality"

Pros: "I was late ( I had to drive 230 Km ) and I managed to call in advance the company that was doing the check-in on behalf of SWISS - I asked them the Check-in time closing time and by almost flying ( speeding like crazy ) I arrived before that moment."
Cons: "I did not check the terms and conditions of the ticket. I am a Star Alliance Gold member and I was expecting SWISS to have a similar booking system like the others I fly with. I found out that the ticket fare did not contain checked luggage ( so I had to pay a hefty fee for it ) and also my 20" wheeled case that was ok in all the other flights I took it with me, this time was oversized and overweight . My wife took out the 2 laptops so it became within weight limits but still oversized - My wife paid for the fee ( I wasn't there at the time and she is not a such experienced flyier as I am ) . When I found out about the fee, I checked their rules and I found out that the hand luggage is allowed to be 22" . I saw in the airplane a lot of people with cases having the same size as mine, that went as checked luggage at a cost fo around 40 . I want to see how can I get my money back . . ."

Cons: "The flight was 1:20 hours delay so it arrived at midnight to Vienna. Even they refused to accept all the cabin bags on board. Very disspointed with Swiss. I’m flying twice time a week and I never experience so frustating experience like Swiss Air"

Pros: "Just like everything else the Swiss do, our Swiss air flight was like a well oiled machine. Very friendly crew, very good meals, lots of creatures comforts; blankets, pillows, headphones, warm washcloths in the morning. Great overall experience."
Cons: "The seat room is every bit as tight as any other airline, so if you're tall, and flying an overnight, upgrading to a seat with leg room might be worth the extra cost. Select your roomy seat early - they go fast!"

Pros: "On time, good service, nice crew"
Cons: "Tight space for legs when chair is in flat setting"

Pros: "Prompt and business like"
Cons: "As a business passenger I was told to go to the Avianca lounge this lounge is not Swiss standards the man sitting next to me was in a t shirt and swim shorts I started flying all over since 1952 most in the back so sorry to see such relaxed protocols"

Pros: "The service was great, the staff was very friendly and helpful"
Cons: "The business seats that we booked were normal economy plus seats with no one in the middle seat. The whole idea of booking a business class ticket is the extra comfort that comes with the lay flat seat or at absolute minimum on smaller planes the wider more comfortable seat. Neither of those were present on this flight. Calling this a business class is a rip off."

Pros: "Was a very quick flight."

Pros: "Very attentive to children at boarding and in-flight."

Pros: "The crew was entertaining and pleasant. The flight was short and easy."

Pros: "I was placed at the very last seat because of a mix-up of tickets, then had to change twice because some people didn't like their seats. Sitting next to your spouse is logical, but best to provide the ability to select seating ahead of time."
Cons: "Landing. Very rough"

Pros: "From my previous flight, the crew informed the flight attendants to LA about my condition. This crew checked in with me every few hours to make sure I was comfortable and had enough tissues and tea to make it through the 12 hours."

Cons: "Swiss staff was not helpful at all at Zurich airport. I wanted to purchase a day pass in the Business class lounge. They said i could do that but need to do it online. When I couldn't get my device to bring up the right screen they said they couldn't help me. Bad customerbaervixe"

Pros: "the entertainment selection was above an beyond."
Cons: "The food was really not great. The meals were tiny and low quality. I understand there are restrictions when on an aircraft, but the meals were the size of snacks and not understanding of allergies at all. (Ie, cheese was on everything.)"

Pros: "Best flight in years. Attentive crew, very good food and wine, on time. Strongly recommended."

Pros: "The food"

Pros: "Food, service, beverages, film selection."
Cons: "N/a"

Pros: "Seat spacing better on the short flight than the long flight -- where is the Swiss logical thinking ---- apparently this is a myth"
Cons: "Swiss boarding is a Charlie Foxtrot"

Pros: "Crew was really nice, comfortable seat, great experience"
Cons: "I liked everything"

Pros: "Nothing"
Cons: "The most racist and unfriendly and uncivilized people ever."

Pros: "Easy and quick"

Pros: "went smoothly on our flight from Zurich to Boston. The flight attendants made all the difference! We would fly Swiss Air again."
Cons: "The arm rest would not raise so it was 100% out of the way on our Airbus 330. This was true for all coach seats in the main cabin."

Pros: "mtl to Zuric was t"

Pros: "The plane was very clean and the flight crew was friendly. The food was very good (as airplane food goes) and beverage service was prompt."
Cons: "The seats were quite hard. The temperature on the plane was very hot. We were unable to access our boarding documents or check-in in advance of our flight. The movie selection was mostly geared toward men - a lot of Bond films. Not really sure what that was about. Our flight was delayed because of complications in Boston and our luggage did not make our connecting Swiss flight in Zurich."

Pros: "Quick flight, nice crew"
Cons: "Snack options"

Pros: "Nothing notable"
Cons: "The crew was quite rude for the duration of the trip and too busy to help. The plane was very old and seats poorly padded- like sitting on stone. Most televisions in our section malfunctioned or didn't work at all. Staff did little to help. Unlikely we would travel on this airline again."

Cons: "I was supposed to put my backpack into "bulky baggage". I couldn't find it. When I got on the flight one of the attendants yelled at me for having my bag. Also the signage was incorrect where we had to go thru with our boarding pass. So I stood in a couple of lines that didn't work."

Cons: "Even though I ordered in plenty of time, I was not on their list. I went hungry."

Pros: "Courteous friendly staff everything went super smoothly!!!"
Cons: "Nothing"

Pros: "Great tasting food and lots of movies to choose from"
Cons: "Wish they would board the plane from the back to the front. Maybe that would eliminate the back up in the aisle during boarding times."

Cons: "The seats. Too packed and very uncomfortable"

"Germán efficiency with boarding; not superfriendly, but appropriate; they were also mask Nazis with wearing you mask even if it had fallen below your nose while sleeping"

"I'm not really sure what the difference is between Economy and Premium Economy on these long-haul flights, especially when the plan isn't very full and people in Economy can lie down across an entire row. The seats in Premium Economy are a bit bigger, but you can't recline or lie down and I'm pretty sure we get the same food options as regular economy. You get a little goodie bag that you don't really need. Also, there is really no point upgrading to business class on the short flights with Lufthansa. The seat size is the same as the rest of the plane. So, you're paying $50 or so for a pretty small snack/meal and a curtain between you."

Pros: "Loved this flight, crew was amazing!"

Cons: "Considering that we’re in the middle of a pandemic no LH ground staff at Heathrow Airport was leading by example wearing protective equipment such as mask or gloves. Further, I found it inexplicably that almost every seat was taken on this flight. If LH knows that the flight is booked close to capacity I would have expected they do their part and due diligence by swapping to a bigger aircraft to help protect people and their customers, it’s not that they wouldn’t have other aircrafts grounded and ready to go... A reduced beverage service is all you can do, really? LH - very disappointing once again"

Pros: "Didn’t like anything. Mediocre all round."
Cons: "Disembarkation took 40 mins due to which most passengers struggled to catch connecting flights. Very poor service by Lufthansa to help delayed passengers."

Pros: "Boarding was quick and good"

Pros: "There wasn’t anything to highlight as good. On this trip except LHR was organized and clean. The boarding was a free for all after the elderly and young had been boarded footstep as they should."
Cons: "The ground staff were rude and officious"

Pros: "Seat and crew were amazing but obviously struggled to be proud and confident of their job, can’t blame them if the company cuts expenses all over."
Cons: "When you fly business class, you expect a different product than economy, because you pay almost double the price. All we got is the same lousy sandwich as in economy, neither are alcoholic or hot beverages available due to ‘shortage of staff’ as the crew announces. A flight far behind LH standards."

Cons: "On tome flight"

Pros: "Nothing at all, whole experience was incredibly stressful"
Cons: "The transfer was awful. Long line for the frankly bizarre security check despite never leaving the terminal, incredibly rude staff at Frankfurt airport, all wearing may we help badges, so kind of answered their own question. Check in staff once we had sprinted th length of the terminal very rude"

Pros: "Crew very helpful."
Cons: "Both flights late. Food was worthy rather than tasty. Seats small. Too much plastic - why not use non plastic cups. Sexist safety card."

Cons: "The entertainment system broke down completely on the whole plane and the crew was sort of grumpy."

Cons: "Boarding by rows would avoid people rushing to line up ahead of time."

Pros: "Staff were ok, did all they could"
Cons: "Not enough information especially for people with connecting flights"

Pros: "Despite the short flight we were still given food and as always I love airline food. Free alcohol is always a bonus as well! Nice crew and timely take offs and landings. Could bring two hand luggage (backpack and suitcase) which I like even though I didn't have to pay extra!"
Cons: "No negatives."

Cons: "There was not enough room for all the people’s cabin size luggage. They allowed people to get on board with big coats once they’re in the plain they take off the coats and place them up. Those coats take the same space as a small suitcase. I asked the fly attendants for assistance and they didn’t even pretend to care about the situation. I had to put my luggage under the seat for the entire flight, which ended up reducing the very reduced legroom. What this airline is trying to do is; to charge passengers twice for cabin size luggage. This has been my worst experiences with airlines. Lufthansa is definitely an airline to avoid."

Pros: "Very explanatory clear and responsive. There was a short delay they kept us informed clearly and responsibly. Excellent flight and superb performance. Very polite and helpful."

Cons: "Flight from Heathrow to Frankfurt delayed, when we arrived we had no chance of making our connecting flight to Split yet no one told us. No one at the gate which didn’t say final call (or on any of the boards) or anyone calling us over the tannoy at any point. Super rude “flight manager” A. Turini burst out laughing when we told him our situation and when I asked why he said “Well would it make you happier if I cry instead?” So unprofessional."

Pros: "The ground staff in Heathrow was helpful. They happily swapped me onto an earlier flight to Munich after I spotted delays out of Munich, allowing me ample time to connect in Munich airport"
Cons: "Lufthansa's narrowbodies have one of the most uncomfortable seats in the sky. These slimline seats are built with a central beam running vertically along the midline of the seat, making it very uncomfortable with your spine."

Pros: "Crew and service was amazing"
Cons: "No entertainment food Horrible"

Pros: "There was no communication between aircrew and gate for transfers. There is a new additional check between gates and no passenger was informed. This security check was over an hour long."

Pros: "I like everything about Lufthansa in terms of quality and service"
Cons: "Punctuality. I fly lufthansa twice a week and I have yet to fly on time. There are always a delay."

Pros: "Once again, the in-flight crew was excellent. The flight was good, but no entertainment is provided."
Cons: "Another late take off, probably because the incoming connections were late. So it was good that the airline delayed the connecting flights. However, this leg of the trip was so late that I barely made it to third leg of the trip. A huge problem is that each of these international airports require that you go through the security check again. For that reason, connecting legs of trips through these airports should not be scheduled so close together. Heathrow is the worst, with security staff that, at best, don’t care that you have a close connection to make and just ignore your pleas to speed up the process, and at worst, are just plain rude."

Cons: "Cancelled flight and transferring me on turkish airlines again the flight was delayed over three hours.,obviously we have missed our connection flight to Beirut and now waiting in front the hotel desk because the first flight to Beirut is 12:25 pm , I have lost 2 days from my holiday,I'm very tired and upset, I will never use kayak ever again and I will tell all my friends and family to avoid it."

Cons: "The flight was delayed . When we arrived in Frankfurt, there was a quie of 200m . After waiting 10 minutes, they asked us to go to other passport control . We had to walk onother 10 minutes to get there ."

Cons: "Not entertainment at all"

Pros: "The boarding process was smooth, take off delayed by just over an hour but the Crew were exceptional with providing updates and bringing around refreshments whilst we waited."
Cons: "Seats were a little uncomfortable but outside that not much I can fault the airline for."

Pros: "One airhostess ruined my flight experience. Anyway in the beginning on the journey my daughter was not well and other crew members gave her candies. I liked the sweet gesture."
Cons: "I was traveling with my daughter. There was no food choice left for my child and me. Crew member rudely said there is only beef option left do you want to have it? I said no. I asked her are we not going to get anything to eat since you are out of options. She continuously kept on repeating that I said no and that she kept emphasizing that there is only beef option left. Finally she save the supplement To meal. Her tone was very impolite when especially we pay so much and service we get for a long flight is good"

Cons: "I didn’t like it because when I asked for a big water bottle, they refused to gove it to me while I am sick and suffer dry throat. The space is rather small. If you are 5ft 5 and above person, I honestly would suggest you buy extra legroom for comfortable purposes. Also, there is like 1 restroom on the whole plane and if you sot at the end, you are screw. Lets not forget that they delayed our flights like 4 hours and only gave us 1 voucher for snack. I don’t expect the experience will be fancy but this is a total disappointment!"

Cons: "It took ages to go through the security check, although I have mentioned that I have a flight connection that is due to leave nobody gave a s..t, so I missed my flight. Now I’m waiting at the airport"

Cons: "Cancelled then delayed then had to stay in Frankfurt and was a day late"

Pros: "The environment was very nice. Relaxed and roomy"

Pros: "The crew were very helpful and friendly"
Cons: "The flight was delayed"

Cons: "Very very long walk plus train to baggage reclaim at Munich"

Cons: "The seats are too close. When reclined it's not possible to get out."

Cons: "Poor food on first leg. Sat by a man who was allowed to have 7 cans of beer. On second leg of journey I was willing to pay for food. The best choice for anyone trying to eat a healthy diet was pot noodles. Air Canada get 2 stars. Return journey on United gets 4stars."

Pros: "It’s nice that Lufthansa still gives food onboard"
Cons: "My Lufthansa flight left with 1hour delay"

Pros: "Smooth process. Regular updates."
Cons: "Late departure."

Pros: "Good attitude"

Pros: "online booking"
Cons: "There is no one at Kayak to answer questions on weekends. Message says "call back during 'regular' business hours" but does not specify what that means, nor what time zone they are in. (BTW, most people travel on weekends so ya may want to consider providing customer service then...duh). When I finally was able to reach someone in order to upgrage to Premium Economy, they could not help me but said they would send an email with an answer to how much that would cost. The email never came. I will never book with Kayak again."

Pros: "Fast-track security, Lufthansa lounge in Heathrow T2 was fabulous, with incredibly attentive staff, flight stewards were extremely polite and also attentive. Great in flight snack and drinks. A real pleasure."
Cons: "The long walk at Frankfurt - but you can't blame the airline for the place the plane docks at."

Pros: "Friendly helpful staff."
Cons: "Delays."

Pros: "I arrived at the airport early and the check in staff offered an earlier flight so I wouldn't miss my connection. Crew was courteous and the sandwich on board was quite good"
Cons: "Slim seats very uncomfortable and legroom too little"

Pros: "The food and drinks was very good."
Cons: "The flight was late."

Pros: "I loved the TVs, food, and the service. The TV's had so much to watch, and made the time pass so much faster. The service was amazing! They came by so often to give us whatever we needed! Great experience!"
Cons: "Nothing"

Pros: "Best part: Getting off the plane and swearing never to fly with Lufthansa again."
Cons: "Flying to Munich- flight was cancelled. Had to rebook on United for the following day. Arrived almost 2 days late (the original was direct, the United had layovers) and missed a planned trip to Neuschwanstein castle. Flying from Munich- The entertainment screen was broken, completely unusable. After a hard reset by the flight attendant several times... Still broken. She said she thought it would fix itself once we were at cruising altitude. Nope. Notified the flight attendant who said vaguely "I'll see what I can do..." Never came back to check, never got offered any sort of compensation (even something like a free mixed drink would have been nice), offer to move seats, nothing. So- ten hours with no entertainment/nothing to watch, just a malfunctioning screen. Food was mediocre. We boarded late, and left almost 1 hour late because they had to wait for an employee (who was not working, just getting a ride back) to board. Literally there and back with Lufthansa was a fiasco. On top of it, we have been back for 3 weeks and are still waiting to hear back from Lufthansa customer service. Apparently they only communicate by email with complaints. Not over the phone. So after repeated emails, just radio silence. Terrible airline."

Pros: "Free refreshments. Funny cabin crew!"
Cons: "There was very confusing and contradictory information on what you can take with you on top of your cabin luggage. e.g. Can you or can you not take a small shoulder bag with you."

Pros: "Good food, friendly flight attendants"
Cons: "Boarding process was torture. Lufthansa invited us to check-in early, but would not allow us to finish the check-in online process the day prior: seemed to be glitch in their computer system. We arrived at the airport early, but no one at Lufthansa could help us with seat assignments in order to seat our 12-yo daughter next to a partent. The airline did not open the gate area until 1+35 prior to the flight (advertised 2-hrs prior), and did not put anyone at the gate-desk until 1-hr prior to departure ...and they still could not help us. Boarding was disorganized; Lufthansa appeared to board by different groups, but there were no announcements as to which group(s) should board. Instead there was just a large crowd milling about, waiting to push their way to a gate agent. Very un-German."

Pros: "Lufthansa is by far the best airline. All crew members were very friendly and attentive. Food was also great."

Pros: "crew at the gate really excellent"
Cons: "usual plane handling at Frankfurt - bus to terminal, 60 mins is not enough to wait for bus 15 mins drive 10 then go through security and passport control then go from B to A leaving no time to catch a plane Lufthansa scheduling need to experience what they do to passengers"

Pros: "Aer Lingus crew are great. Probably some of the nicest people in the world. Lightly loaded so boarding was quick and staff were lenient about cabin baggage."
Cons: "My 757 is among the oldest aircraft in service, and it shows. Noisy and every surface is well worn. Seats are substandard in the industry for a long flight. Granted the flight was lightly filled, so that made it a bit nicer."

Pros: "Everything was easy and the crew were really nice."
Cons: "Both transatlantic flights I had requested lactose-free meal options, neither of which happened."

Cons: "Not much legroom"

Cons: "My bags did not make it to the destination. This caused me to miss a bus and train."

Cons: "Lost my bags"

Cons: "fly cleanup"

Cons: "The seats were very tight and narrow"

Pros: "Nothing was pleasant for this flight"
Cons: "Keep the schedule up to date on the web When there’s delay, keep customers posted Don’t miss customers luggage"

Pros: "Nothing"
Cons: "Food"

Cons: "Flight was good. Kayak service terriible. First time user and I’ll never use it again. Who wants to deal with a third third part. Information was not translated properly and resulted in my wife and I on separate flight."

Cons: "We got to gate after standing in the lobby 30 min prior to take off and they wouldn’t let us in gate . We were in the air lingus lounge waiting for the flight and the gate attendant said she called our name on speaker which she did not . We get to gate and they say we are no longer able to board the plane"

Cons: "My granddaughter and I were seated with a guy who reeked of really bad body odor that I was retching in my seat for the whole flight. The flight was full."

Pros: "No delays. Reasonably comfortable"
Cons: "Not a single vegetarian option on the flight ??!?"

Cons: "It was very hard to hear the boarding announcements at the gate"

Pros: "Staff held the plane 30 minutes to allow us to make the flight."
Cons: "Its hard to sleep on the plane when staff"

Pros: "The staff was very friendly and accommodating. Very punctual."

Pros: "The check-in at JFK was super fast and efficient. Everyone was very pleasant and helpful. Also, had a connecting flight and my luggage arrived with me-big plus."
Cons: "Seats were a little tight."

Pros: "Quick flight, great landing"
Cons: "Can believe they charge you for water."

Cons: "Very dirty. Waste in the seat back, gum on the floor"

Pros: "Direct flight LAX to Dublin with no lay overs"
Cons: "No toilet paper or paper hand towels in the bathroom. Early on in the flight I went to ask for toilet paper and was given a nod. Tried a different bathroom and no toilet paper there. Servicing the toilets on the full flight was neglected."

Pros: "TVs on seat-backs, good selection of movies and television, USB charging outlet on seat-backs"
Cons: "Every seat came with useless headphone sets: the jacks were for an older model of plane. Flight attendants warned passengers that they had some headsets that would work, but were keeping them reserved for children, so not to bother asking for them. Flight took off more than 3 hours late and airline took no responsibility for delays. Blamed LAX contractors for everything. The airline is responsible for who they do business with. Because of takeoff delays, food and beverage service was also badly delayed. Had to beg for water several hours in, and was brought a single small cup."

Pros: "Seats were larger with more leg room. Flight calm and without incident"
Cons: "No snack"

Pros: "Crew were great"
Cons: "Delayed Dublin to Newcastle flight"

Cons: "It was fine, but once again, not able to choose or upgrade seats."

Pros: "I had a good flight. No complaints."

Pros: "The only thing I can say that I liked about this flight was that we arrived a little early."
Cons: "Note: This review is for Aer Lingus a partner of British Airways. 1) Service - one of our fight attendants was incredibly rude. She clearly resents her job. 2) The plane itself was very old and not well maintained. The audio jack for the in-flight entertainment was broken and I could not watch anything. My wife complained about the touch screens being faulty and her audio system was bad. Also, the carpet and seat fabric was torn. 3) The food was disgusting. I mean, really bad. 4) There was a charge for alcohol whereas British Airways was complimentary. 5) Overall, I will never fly Aer Lingus again. It was the worst flying experience in memory."

Pros: "Boarding was quick."
Cons: "They lost my luggage on my connecting flight from Dublin to London. And I didn’t receive it until I returned home a week later. No clothing for a week. I wasn’t offered any reimbursement. The flight attendants were rude. And the seats were uncomfortable."

Pros: "Food provided. Enough overhead bin space for bags. Newish plane. On demand entertainment screen."
Cons: "Couldn’t change seat at checkin so couldn’t sit next to husband on a separate reservation. Not many new movies."

Cons: "Most uncomfortable flight ever"

Pros: "Crew was pleasant. Food was OK and service too. Boarding was fine."
Cons: "The 4 hours wait before my connection, the extra security selection that got me all patted for the 2nd time."

Pros: "Flight attendants were excellent."
Cons: "Food was so so. Entertainment selection was so so. Entertainment technology was substandard."

Pros: "The service was wonderful ! I’m handicapped and I was treated very well!"

Pros: "Everything wa on time"

Pros: "Friendly crew"
Cons: "(1) boarding chaotic, misinformation (2) cold cabin, no blanket (3) entertainment system very slow, map not working (4) Overpriced wine and beer on transatlantic segment while competitors serve those free of charge"

Pros: "The flight was delayed by a little over an hour, but the pilot managed to make up some time. Airplane was clean enough and crew was friendly."
Cons: "No free coffee"

Pros: "Reilly dolly"
Cons: "The other trolley dolly"

Pros: "I liked the in-flight crew. They were very pleasant and helpful!"
Cons: "The delays! The check-in app was down and the ladies at the desk didn't seem to be in any hurry to make sure we didn't miss our flight. It was the worst experience."

Pros: "Very helpful and exceptional in flight staff. Ground crew helped us through customs very quickly and made flight transfer very easy."

Pros: "Crews attention to sick passenger"
Cons: "Coffee 3 euros? Pay for everything?"

Pros: "Great airlines!!"
Cons: "No gluten free options"

Pros: "The crew was very helpful and after becoming ill after eating the meal, one of the flight attendants was extremely nice and checked in on me from time to time to give me water."
Cons: "The special meal I received actually made me quite ill. I highly recommend bringing your own food on board or purchasing the snacks on the flight instead."

Cons: "Our son's luggage did not make it to Barcelona with us. We arrived on Sunday. He was called Monday that a delivery service would bring to him that evening, but they did not show up. They were to come Tuesday morning, Tuesday evening, Wednesday morning and never showed up. He finally had to take a $35.00 cab to airport to get the luggage. NOT a good experience. The Aer Lingus support number just rang and rang, no one picked up for days! My daughter tried the main Aer Lingus connection but they referred us back to the same phone number. NOT good customer service."

Pros: "Flight back to NYC was packed. Seats were tight and smaller (width-wise) than Aer Lingus flights out of NYC. Couldn't lean back for fear of being in the lap of the person behind me! Meals and beverages were good. Was surprised by that. Airline personnel were really friendly and nice. We arrived at least 1 hour and 25 minutes ahead of schedule. A+ in my books for that! And fast boarding."
Cons: "Small seats. Could remove a row or two to give more leg room; especially on overseas flights. No USB jacks in economy to charge up devices. Only available in 1st class and business (not fair when more folks in economy section). Okay movie selection. Would have preferred my own screen at seat. Remote kept popping up in arm rest."

Cons: "nothing"

Cons: "Since my ticket was with British Airways "Operated" by Aer Lingus, I was not the only one confused about which airport terminal to go to. The taxi driver was confused too. He was not sure he had dropped us at the right place. Even the person at the Information Desk at the airport said it could be unclear for someone "not in the business". Please rectify. Thanks"

Pros: "Excellent service, friendly crew ."
Cons: "Nothing to do with airline or crew, didn't like crying children."

Cons: "Seating was cramped. Food was fair at best."

Pros: "Love aerlingus staff. Very kind!"
Cons: "Not the flight but Vienna airport experience and Dublin airport check in after arrival. Took an hour to go through passport check where one of the staff took forever and was very unfriendly. Only two staff to manage passports for hundreds of visitors."

Pros: "The landing was very smooth"
Cons: "It took a very long time to get off the plane"

Pros: "The flight itself was pretty quick and fine. They sold lunch onboard, which was pretty reasonably priced and pretty tasty."
Cons: "The flight was delayed in Venice by over an hour, and none of the staff there ever gave any announcements or updates to let us know anything. They didn't even say that the flight was delayed, they just never announced boarding. Very different than the service Aer Lingus staff has provided at other airports."

Cons: "It was too warm. The air above was not cool"

Cons: "Small not comfortable plane"

Pros: "No crew was amazing, they were her it attentive to our needs"

Cons: "The check in and boarding process is always slow and cumbersome at Keflavik - it’s unpleasant to have to be bussed to the plane outdoors and then use stairs to get up to the plane."

Cons: "There was no food included. I was onboard for over 9 hours total and no included food."

Pros: "WE ARE STILL NOT HOME. WAS ORIGINALLY SUPPOED TO GET HOME AT 6P LAST NIGHT BUT BECAUSE OF CANCELLATIONS WE ARE STILL STUCK IN CHICAGO’S AIRPORT AND IM NEVER BOOKING THROUGH KAYAK OR KIWI EVER AGAIN. GETTING MONEY BACK FOR THIS BEYOND SHITTY EXPERIENCE STILL WOULDNT BE ENOUGH TO MAKE THIS RIGHT."
Cons: "THEY CANCELLED THE FLIGHT CAUSING US TO STILL BE TRAVELING OVER 24 HRS LATER"

Pros: "I really like Iceland air and have always found them to be the best but I can’t say this flight was very enjoyable"
Cons: "Plane had the least leg room of any plane I have ever flown on. There was no entertainment which was good since I couldn’t even put my tray down when the person in front reclined. Seats very uncomfortable. Staff didn’t seem like the usually very friendly Icelandair people"

Pros: "Crew was great, seats were comfortable, plenty of space"

Pros: "When I booked my Economy Light fare from Denver to Paris, I was expecting a trying experience. But to the contrary, I found the entire trip to Paris and back enjoyable. I found the boarding quick and efficient, plus the flight attendants were genuinely friendly and helpful."
Cons: "Short answer: Nothing. Icelandair is my new favorite low-cost airline for trips to Europe."

Pros: "Crew was very helpful and friendly, and we were greeted with a bottle of water for the flight. Entertainment is nice with free movies, music and Iceland travel video blogs. Water/soda/coffee offered multiple times, and water additional times."
Cons: "Boarding was walk-to-outside-stairs, more an airport versus airline thing, in truth the fresh air was nice, just glad it wasn't pouring rain. Seat comfort was barely okay, the 757 seats were basically in contact with my knees, tough for such a long flight. Their 767's are much better. Didn't like paying 60 GBP (pounds, about $75) for 3 sandwich lunches with 3 alcoholic drinks, IcelandAir could do better."

Pros: "Entertainment center has newer releases"
Cons: "Extra baggage fee, no space for carry on, boarding zones 1st to 5th - no bin space within 5 rows by the time zone 5 boarded"

Pros: "I loved that when I checked in online I was given the opportunity to take a seat with extra leg room. Service was great."
Cons: "The connection in Reykjavik does make the flight from Gatwick to Washington rather long but it also gave me the opportunity to see some new views and stop off for a tour on a previous flight."

Pros: "plane was comfortable, smooth flight"
Cons: "could use more up to date movie selection, crew did NOT smile, food was at an extra cost"

Pros: "Ok price"
Cons: "No checked bags included, but this was unclear at the time of purchase, even though it was an international flight."

Cons: "Charging for every moment of the experience is certainly one way to go for Iceland Air. I get that their economy hit rock bottom, but this isn't the way to get out of global financial crisis."

Pros: "The lights in the cabin were great set up to look like the Aurora"
Cons: "Offered 1 drink and no snack. Rarely do you see the crew on their flights"

Pros: "After a long journey overall, it was nice to have an easy plane ride to Iceland!"
Cons: "N/A"

Pros: "Excellent in-flight entertainment."
Cons: "No complimentary meal for transatlantic flight."

Pros: "Movies, price"
Cons: "Not getting food!"

Cons: "My flight was delayed an hour and a half with no explanation so I almost missed my connecting flight even after sprinting through the airport. I called for a reason why it was so delayed and the customer service rep had a poor attitude and offered little help."

Cons: "Food offerings for 7.5 hour flight very limited, and not complimentary. This was not communicated when I booked the flight (would have considered using a different airline). Entertainment options were limited compared to other airlines' long-distance offerings. Only two beverage service in 8 hours, no complimentary snacks, and each time I wasn't given the entire can of soda, just poured a small glass. Pretty skimpy. My family members who used different airlines got a much more for their money, with similar ticket price. Flight took off late and we did not make up time in the air so we arrived an hour late."

Pros: "Tickets were much less expensive routing from Newark through you'll "pay" on the end."
Cons: "Reyk is growing faster than it's ability to manage it's flow of passengers. Expect a lack of seating for gates; heavy passenger jams in the terminal, and lengthy waits whilst standing in hot, stuffy, packed busses before boarding. Don't assume the prices (Kr) at the Lagarde terminal shop are reasonable: water bottle=$4, beef stick=$8, 2×2" granola bar=$6, personal pizza=$17, small bag of fried fish crisps gullskifur=$13. Bring food and water from your previous stop and eat your food near the check-out whlist watching the facial expressions of the travelers who are paying their bills at the airport shop."

Pros: "Icelandair's seat headrests are very comfortable for sleeping."
Cons: "The Reykjavik airport, although it has nice restaurants, is ill equipped to handle the number of passengers going through it!"

Pros: "Crew was helpful and competent. Smooth flight and easy security after night of terror attacks in London 03June2017."
Cons: "No entertainment for a 3 hour flight? Not even a free bag of nuts? Free beverage came 1.5 hours after takeoff (several paid cart runs came first). Should've been like other flights where you get a small water bottle upon boarding."

Pros: "Size of the Reykjavik airport."
Cons: "Not enough space for legs in the economy class. The chair back support was not working correctly ( couldn't be blocked in the reclined position). Very uncomfortable chairs overall. No food included in the price of a ticket for such long flight? Poorly organized and managed departure process. The passenger next to me was sick looking. He was coughing loudly and frequently all the time during that flight. For more then 7h of the flight no flight attendant demonstrated ANY interest or offered any help. Furthermore when his female companion (wife?) asked just for cup of water so he could get his meds at the beginning of the flight they were told to wait for the regular service to start (what took app 30min). So overall my impression of the Icelandair service is no more then just O'k."

Pros: "The separate cabin"
Cons: "The business seats did not have leg elevation & did not lie flat making sleep difficult. Comfort was compromised since I could not elevate my legs"

Pros: "The seats were comfortable with more leg room than on American airlines--important for me because I'm 6/2". Entertainment system worked very well. Plane had a new feel--clean and classy."
Cons: "I didn't like that food was only available if paid for. I was not aware of this before hand. If one is aware, one can bring one's own food."

Pros: "New planes nice staff"
Cons: "Uncertainty of arrival connection, we have a flight in a month with a tight return schedule. It was disconcerting."

Pros: "We normally really like flying Icelandair and enjoy the ability to have a stopover in Iceland. The crew is always very nice and this flight was no exception."
Cons: "The plane, or at least our section of it, was very warm. We were near the doors between Business Class and Economy, so we were expecting it to be even a little cold, but it was so warm that I was in a tank top the entire flight. The boarding process in Reykjavik was very odd, even for them. There was just a door in the wall under our gate # and without warning it was opened and everyone just got up and went through it. There was no announcement. Apparently the checkin desk was upstairs. We then waited 20 minutes in line, before they finally started boarding us int he order we were queued - again, no announcement."

Pros: "There was more leg room that we thought there would be; we were left alone to sleep by the attendants. The pilots let us know important information."
Cons: "We were 3 hours late to Denver after leaving Iceland late. This was partially due to weather. The only upsetting thing was the $31 "dinner" available in the airport consisting of a frozen individual pizza, sandwich and 2 waters! We felt like we were being gouged for the airlines issues. The entertainment system on this flight from Iceland to Denver was a bit old and of all four flights, the system was difficult to access."

Pros: "The entertainment provided was great, the seats were fairly comfortable and the flight crew was great"
Cons: "My friend flew Delta to our same location at almost the same time for a slightly cheaper fair and she received two free meals and two hot towels aboard the flight. I wasn't expecting to have to pay for dinner. Otherwise I would have brought food on."

Cons: "Small new movie selection. I flew to London in late November and returned in early December. I thought some new movies would be listed in December but that was not the case. Although I have found most Icelanders speak very good English, oddly enough, the accent of the person making the English announcements on the flight made it difficult to understand the statements."

Pros: "Friendly staff"
Cons: "There is only food for purchase on this long flight, and they ran out of vegetarian option before they got to me."

Pros: "Sat in exit row for the leg room but ended up with a bruised tailbone from the seats cross support. Could barely sit for a week"

Pros: "Crew was very professional and responsive to a difficult weather situation at the airport in Reykjavik."
Cons: "Admittedly this is something of an airport issue more than an airline issue, however considering Icelandair is one of the few airlines servicing the airport in Reykjavik there has to be some level of coordination going on between the two entities. Regardless, 5 different US-bound flights were all scheduled to leave within 15 minutes of each other in the same small corner of the Reykjavik airport, so when delays started coming in due to weather that area became an extremely congested mess. Perhaps its a cultural norm in Iceland to just remain silent in times of mini-crisis, but the desk attendants made no effort to communicate what was going on to the hundreds of people crammed in atop one another in the waiting area. This led to a lot of frustration from the waiting travelers. Both of these problems could have been prevented by better planning (not scheduling all outbound flights happening in a quarter hour's time into the same small corner of the airport) and better communication from the airline staff, the lack of which really aggravated a difficult situation for the people there. Once on the flight, though, everything went very smoothly, and the flight crew was quite apologetic and professional."

Cons: "Boarding was late. Head phone Jack didn't work and seat recliner wouldn't stay back"

Pros: "On time service. Video selections. On-board wi-fi."
Cons: "1. Same comments regarding cramped seating as above. 2. Boarding in Reykjavik was a total fiasco. Management should visit a European or US airport to see how to load a plane in an organized fashion, as opposed to the free-for-all used in Reykjavik now. 3. Food selection for an over water flight of 7 hours was abominable! And passengers are asked to pay for it too...unheard of for trans-ocean flights."

Pros: "The in flight entertainment"
Cons: "The crew were rude and unwelcoming. Having to actually PURCHASE food and drinks on an international, transatlantic flight is ludicrous. Having made the trip from the USA to Europe many, many times, this was a shock and something that i didn't prepare for. The cabin crew were extremely rude and uncaring. Being offered a drink of water once in 7.5 hours is ridiculous and frankly dangerous for some. This was not a cheap flight, so for such poor service, I think things need to change. A smile from a crew member may not go a miss either. Thanks Icelandair, but i shall not be choosing you for my travel needs in the future, and neither will my friends and colleagues."

Cons: "When we arrived at Keflavik airport the terminal was immensely crowded with several flights due to leave the US at once. It was overcrowded to the point of being uncomfortable and there was a 30min+ wait to buy food from the only shop. As a result we did not have time to grab a bite to eat between flights. My partner was subjected to additional TSA checks which I am aware is a random check and a nescessity but due to the amount of flights departing for the US this took an extra hour, and delayed our flight. I'm thankful that Iceland Air didn't leave without us but it was an immensely stressful experience that I don't wish to go through again."

I'm thankful that Iceland Air didn't leave without us but it was an immensely stressful experience that I don't wish to go through again."

Pros: "Nothing to like except that we finally got here."
Cons: "Late departure. Not enough fuel in plane so had to refuel in Minneapolis. Even with headwinds, there should have been enough fuel put into the plane to complete the trip. They stopped in at an airport that was experiencing thunderstorms, and while we were refueling, our plan was struck by lightening and then had to to be examined for damage before continuing on. We were on the ground, in the plane, for a total of 4 hours, waiting. Finally were advised that the crew had "timed out" and could not fly any more that day, so we spent the night and all the next day sleeping on the floor in the airport. Icelandair was not at all prepared for such a situation. Situation was somewhat chaotic with incomplete and inaccurate information given to passengers. Very poor communication on the part of Icelandair, or whoever they contract this function to. We expected to be able to leave the airport the next morning, but were told that the flight would not leave until 5 p.m. Then they changed the time to 8:20 p.m. but didn't announce that. Then that flight delayed until 9:00 p.m. We finally got off the ground a little after 10:00 p.m. On top of all this, many passengers' entertainment systems did not work, and this made for a very long and frustrating flight. Not good, Icelandair."

Cons: "Our plane was diverted to refuel - after an hour and a half of increasingly cryptic and contradictory communications while sitting on the ground, we were removed from the plane and given cots to sleep on the airport floor. No staff present to provide information, no communication by email, noone available by phone, no updates on the website, vague rumors from another airline's staff of a "possible flight" the following evening.....no idea how/when we'd get back to Denver. We got a car and started driving...huge vote of no confidence in Iceland Air, its equipment and staff."

Pros: "Crew was pleasant. Leg room was better then on airlines in the U.S., and it was much easier to get out of the seat with the armrest lifting mon the aisle seat."
Cons: "The boarding process was difficult, as four flights to the U.S. were leaving at the same time and it was almost impossible to get to the gate because of the thick wall of people and no aisles. We were then put on a bus to the plane, but the bus didn't leave for over 30 minutes, well after the takeoff time, and no explanation was given. The temperature on the plane was extremely uncomfortable. Most of the time, it was very hot, and I am accustomed to flights being on the cool side and requesting a blanket. But someone must have been adjusting the temperature, because it would get cold for a short period of time, and then very hot again. It was difficult to sleep because of the temperature. It would have been nice to have some small snacks like pretzels offered with the drinks, and a larger selection of food available."

Pros: "Entertainment very good - lots of good movies that I had not seen. I love that there was not an extra charge. The service on the flight was good."
Cons: "The boarding process in Reykjavik was just awful. First we had no warning that Gate D would require such an extensive wait, so we spent too long in terminal eating and then panicked that we might miss our flight. Next there was a problem boarding our plane. There weren't enough buses, so we spent over an hour standing in a cramped line that snaked down the hall in an extremely crowded airport with people trying to squeeze though us. It was really uncomfortable. The worst was the crew waited to process people and send them in to the waiting area until a bus arrived, so this added to the wait time. I think tourism is popular in Iceland now and you all need to figure out how to make your systems better. I loved Iceland but I wold seriously need to think hard before booking another flight with you."

Pros: "Made up some time since the flight was delayed."
Cons: "Much longer delay on the next flight to JFK after already having an original delay at Gatwick. Keflavik airport wasn't able to accommodate the number of travelers with delayed flights that day."

Pros: "They upgraded my to economy comfort, which made all of the difference for an 8 hour transatlantic flight."

Pros: "Crew was very nice, most of the planes were in great condition, great movie selection."
Cons: "Very confused why there was no food."

Cons: "Flight was delayed leaving Reykjavik. I watched our baggage be removed from the plane and head to the opposite side of the airport. It was over 30 minutes later that they announced that there was a mechanical issue with our plane and we had to switch planes. The passengers deplaned, boarded buses and were transported to the new plane. We finally took off over 2 hours late. The other major issue we had is that we were located near the back of the plane and the smell of urine and toilet chemicals was overwhelming. Every time the restroom was used, the stench permeated the back of the plane."

Cons: "See above. On the flight from Denver to Amsterdam (you didn't ask about this, but I'll comment anyway), we had business class seats. They were really little more than large regular seats with legroom. We did get food on the flights, unlike the economy class. I have a major gripe about Icelander not telling you how their definitions of seating class differs from the rest of the Western airline industry. Quite deceptive."

Pros: "The previous Icelandair flight from Paris to Reykiavik was late and arrived over an hour after the scheduled departure time for the Reykiavik to Denver segment. We were assured that the flight would wait for the late arrivals, and it did. We were, of course, greatly relieved. I can't help wondering, however, How could a scheduled flight be held up for this long and how would the passengers already on the plane feel."
Cons: "Only drinks like water, tea, coffee and juices are served free on Icelandair flights. There is a menu for sandwiches and snacks. But the selection is rather anemic for a 7 hour long flight."
