Airline reviews

Pros: "The crews were super accommodating and my seat was so comfortable I actually feel asleep which is something I have never done on a plane before."
Cons: "Load the plane from back to front. It makes sense as people leave the plane from front to back"

Pros: "Good"

Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."

Pros: "In flight entertainment"
Cons: "Food provided, other than snacks, would be a plus"

Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."

Pros: "Comfort + was nice."
Cons: "Had a middle seat between two other men. I was given my seat by the gate. It would have been nice if they placed my more strategically. That might be asking too much but seems reasonable."

Cons: "Choice of healthier snack"

Pros: "Nothing spectacular."
Cons: "The headrests won’t stay up. And it’s hot."

Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."

Cons: "Seats are so small. Flight was delayed."

Pros: "Staff from Check in to aircraft very pleasant. Snack choice in Coach impressive."

Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

Cons: "Had to wait for the crew from another flight before boarding p"

Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."

Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."
Cons: "The landing was pretty tough and we took off almost a half hour late."

Pros: "Check in Denver super helpful Gate staff hustled to turn around flight Flight crew excellent"
Cons: "Flight delayed, almost missed international connections"

Pros: "Boarding, friendliness of staff"

Pros: "Everything was easy and smooth."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Pros: "The staff was polite and snacks were good (healthy options)."
Cons: "Nothing was terrible, but due to the short flights I assume they don’t worry about having planes with entertainment available."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Cons: "Engine problems-2 hour delay"

Pros: "Good flight crew"
Cons: "Delayed due to mechanical issues. For 3 hours. No offers for free drink or wi fi. When we finally land we were on the runway for half hour."

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."

Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "Most comfortable flight I have taken in some time. Spacious seat, power, good entertaiment, attentive flight crew. On time. Not usually a Delta flier, but times and destination made Delta the choice. Turns out a great choice."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Crew was the best!"
Cons: "I really dislike the snack boxes. Snacks need to be more like a small sandwich or grapes, cheese and nuts. Not all that packaged stuff."

Pros: "Boarding super excellent! Also: Best landing I've ever experienced! Props to the pilot!!"

Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Pros: "Excellent crew and comfortable flight"

Pros: "Friendly Staff"
Cons: "Check in was very hectic due to limited staff and getting bumped by the red carpet flyers. Boarding is always a little congested due to the lines. Better snacks please!!"

Pros: "We purchased economy tickets in Delta. With these tickets you don't know where you are sitting until you get to the airport. Well, we lucked out and got the Plus seats! We got free alcoholic drinks, and big plush seats! We left right on time and got there early! Overall a great experience!"
Cons: "Nothing."

Pros: "Great,I loved it!"

Pros: "The moviea"
Cons: "The time of night"

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "Entertainment options"

Pros: "Upgraded to first class"
Cons: "No entertainment system, no power outlet...for first class this is disgraceful"

Cons: "Kayak is a horrible company and not easy to work with. They have screwed me royally and I will say nothing but bad things about them. They should not even be in business the way they have handled my situation including hanging up on me multiple times and changing the rules for flight changes, etc. Saying I am unhappy is an understatement."

Pros: "Friendly and helpful crew"
Cons: "Disembarkation at Belfast"

Cons: "Only item that could be better is quality of onboard entertainment."

Cons: "Lost baggage"

Pros: "Had a fantastic flight and the crew was nice."

Pros: "On time flight, no problems."
Cons: "Seats more cramped than would be ideal for a trsnsatlantic flight."

Cons: "Told us to pick up stroller in Dublin. Get there and we are told that is not possible. Of course we not have arrived at our final destination without said stroller. Seats are on the pitiful side of the spectrum and gets a bit old being nickled and dimed for drinks, sodas, food. . ."

Pros: "Quick easy boarding. Quality Captain and staff"

Pros: "Flight on time"
Cons: "Upon check in Dublin there was only one attendant at the check in counter in business class. Had seat assigned when I booked the flight and check in counter gave different seats so was not sitting beside my husband."

Pros: "Nothing"
Cons: "Aer Lingus made us miss our flight and has us still waiting for a resolution after 22 hrs. This is the worst airline ever!"

Pros: "Nothing"
Cons: "Aer Lingus didn’t have a plane to fly us Dublin you boston so they leased one from a company. Someone from AL walked around gate area handing out a letter with the information. No announcements made that flight was going to be late. Everyone was lined up to board, no que so it was a mess. 49 min of standing there. No announcement plane was going to be late etc. Let us board but stood in jetway for awhile. Old plane. Mediocre service. no entertainment."

Cons: "This was not a British Airways flight. They should have done a better job of communicating that. I wasn't informed until I tried to check in online 24 hours before my flight."

Pros: "The flights themselves were nice. Food was fine. Flight attendants were helpful"
Cons: "Getting to our connection was awful. Prescreening getting into the US was terrible. Got selected for special screening and the officers said the gate knew we were held up there. Only had one hour to reach connection. Lost an immense amount of time getting swabbed and patted down. The gate was closed when we arrived. Had to run to the gate. By accident we found out the gate was closed from someone who happened to hear word that we were looking for the gate to JFK. Almost didn’t get on the flight. If we didn’t run who knows if we would have made it. If you are only giving people an hour to get to their connection, then don’t let them get held up for 40 minutes. It’s idiotic."

Pros: "Great service from entering the airport to leaving. Flight a little bumpy at times.."

Pros: "Aer Lingus service was good and efficient from check-in to arriving."
Cons: "Little time in Dublin to get to our connecting flight to Lyon. Security check was understaffed with long queues."

Cons: "They lost our strollers which put us into a really difficult situation, since we had to carry our two toddlers + our infant during the 5hour connection time in LND."

Pros: "Once airborne the flight was quite enjoyable. Crew were all nice."
Cons: "Flight from Dublin to Seattle was a bit late getting off the ground. First flight from Lisbon to Dublin was on time"

Pros: "Flight was great and very friendly staff. Not sure why I couldn’t check in online."

Pros: "Pretty good flight for a good price."
Cons: "It would be so nice to have tea and/or coffee served before landing. oming in at 5am or 1am North America time is difficult and if you have to travel more that day a cup of coffee or tea sure would help. Serving tea and coffee at ten pm after serving dinner isnt good if you want to sleep..just keep it warm and serve it before we land."

Pros: "Never made the flight"

Pros: "everything was fine"

Pros: "They offered snacks, drinks and movies for free."
Cons: "They had free movies and tv shows but you had to buy plug in headphones. So just pack your own. (Jetblue) Aer Lingus offered headphones, pillows, movies (not a great selection though) and some horrible food."

Pros: "Service, friendliness. The cabin crew seemed like truly genuine, nice people."

Cons: "Only 1 checked luggage was included. I’ve never heard of that for an international flight."

Cons: "the food was really expensive"

Pros: "The flight crew arranged for assistance at the arriving airport."
Cons: "The staff at EWR took the wheelchair that I was in and told me that someone would be along with another one. One never arrived. I went to the desk when boarding began. I requested a wheelchair and I was told that I could walk down the ramp without assistance by one of the boarding staff. I was able to but with great pain and much energy. If it had not been for the crew of the flight I probably would never fly on Aer Lingus again."

Pros: "no delays, comfortable seats"
Cons: "The flight attendants went right past us never asking if we wanted anything. They served the people to our right and in front of us. Mystifying."

Pros: "Prompt Rebooking. The new schedule was better the original schedule with fewer connections."
Cons: "My original flights from Dublin to London and London to Munich were cancelled. The booking agency Webjet did not inform me about the cancellation. I noticed changes to my schedule three days before the flight and requested a rebooking. The entire leg to Munich was rebooked by Webjet but again I had to call and ask for an update since they don't issue a second round of confirmation emails."

Cons: "Would like to be at least able to state a seat preference. With a tendency to be claustrophobic, a middle seat is the worst. Fortunately it was a short flight"

Cons: "No comp food or even water. ridiculous! Limited service, and nothing to make up for it. Nobody from Aerolingus to deal with the lost bag. REALLY!????"

Pros: "Wonderful"

Cons: "See dislikes followig Dallas to Paris"

Pros: "Cheap Flight, Cheap Service & Cheap Review. I got what I have paid for. That is OK."

Cons: "Lost my luggage for two days. Follow-up on lost luggage was extremely poor. As far as plane flight: No place to charge phone on transatlantic flight. Charged for *all* food and drinks including 4 Euros for cup of tea! Plane was very late leaving, and very late arriving. Plane seats were significantly smaller than on other airlines' international flights. Can't see any reason to fly Aer Lingus again."

Cons: "Staff at Frankfurt desk rude and dismissive. Spent hour and a half there...spent hour and a half today replacing clothes. Using faulty gps as you have lost my I-pad."

Cons: "That we paid for breakfast for that segment. Cramped & I'm average."

Cons: "I hate the fact that I was not informed that I needed a transit visa to board the flight from Dublin. The service was poor from the beginning to the end . My ticket reads BA but yet it America and Aer Lingus. Kayak should have made clear from the beginning. I was detained in Ireland. Almost missed my flight"

Pros: "Flight crew was very friendly. Seats were comfortable. Boarding went smoothly. You have to pay for food and drinks, but that doesn't bother me. It clearly mentioned this when booking. I would rather pay less for the flight and purchase my food at the airport or before arriving at the airport."
Cons: "I have no complaints."

Pros: "Short flight so not too much to worry about."
Cons: "Took carry on at gate. Not even water served."

Pros: "The price and convenience was great, airline was well kept with minor technology issues. Restroom facilities were well kept and food was adequate (what airline food is really good?) turbulent flight but the pilot did a goood job maneuvering around."
Cons: "The headsets provided for international movies sound quality was very poor.my daughter and I found ourselves using a single prong (airline headsets require two one for each ear)headphones from our phone to listen to movies with only one in. One flight attendant was not pleasant and wound up spilling a full cup of water on my lap, followed by another hitting me with the food cart. I am a frequent traveler so for me this shouldn't sway anyone's opinion on a minor instance."

Pros: "Serviceable flight."
Cons: "Unable to check in 24 hours before the flight."

Cons: "Paying for the cup of teA seems a bit mean"

Pros: "It was like flying Southwest Airlines; No first-class; no business class; all one class."
Cons: "Absolutely terrible food choices; and for pay only. Very disappointing."

Cons: "Food wasn't very enjoyable. Breakfast was very disappointing."

Pros: "The flight crew was wonderful"
Cons: "inability to get seats ahead of time - sat in rear of aircraft - cramped. I would have liked ability to pay for upgrading seats for more room. In-seat entertainment was glitchy much of the flight."

Cons: "Late departure on way back"

Cons: "No veg food. Crew was not accomidating."

Pros: "The crew was friendly."
Cons: "After the main meal there was a four hour gap before any refreshments were offered, just an hour before landing. For an 8 1/2 hour trip, water should. E offered every two hours!!"

Cons: "Everything was perfect"

Pros: "Boarding from back and rear of plane made passenger loading faster. I had to purchased seats with more room to provide comfort for long flight."
Cons: "In Dublin, we were sent to an area for a long wait with no decent food at all, even though the Dublin airport has good restaurants. It probably has to do with U.S. security, but certainly something more accommodating could be worked out. They had an Aer Lingus lounge, but only for business class and gold card holders, so after spending thousands on tickets, we were not allowed in. Guess the "1 percent" privileges."

Pros: "Poor"
Cons: "Poor"

Cons: "The food was not as usual."

Pros: "Easy boarding, entertainment"
Cons: "Crew was not very friendly on bot departure and return flights. Will make me reconsider Air France in the future."

Pros: "Great and friendly crew"
Cons: "In-flight system had some problems and seats seemed a bit uncomfortable"

Pros: "The crew was great"
Cons: "1-2 +cms leg space"

Pros: "Na"
Cons: "They have a terrible communication problem, they never communicated why the flight was late, they never communicated what they were doing or what was happening. Bad customer service. Bad communication with the client. They told us when I asked several times that we would not lose our connection and that everything was fine and that was not the case. We lost the connection. No one told us anything. Another problem was that the girl in the boarding process removed the suitcases tickets from the boarding pass and did not want to return them, and held it without any cause. The flight staff went looking for us. Pretty sad and disappointed by their service. I understand that they were causes outside the airline but must communicate to the client. They cannot remain silent and say nothing."

Pros: "The seats were spacious and the crew was wonderful. The crew actually made the long flight more tolerable. Will seek out Delta/Air France for further international flights."

Pros: "Nothing"
Cons: "Everything"

Cons: "Flight was delayed"

Pros: "The seat was very comfortable."
Cons: "My boyfriend and I were required to gate check our carry-on luggage which required us to go through customs in Paris to get to our bag and re-enter security for our connecting international flight. I am unsure why this was the case as other passengers brought the same size luggage. Very upsetting."

Pros: "I like the comfortable seats"
Cons: "Service lag a little"

Pros: "Great newer plane, great service!"

Cons: "CDG airport in Paris is a very inefficient and by far the slowest airport. I recommend other passengers to get to the airport at least 4 hours before their departure."

Cons: "More options for gluten free food. Always get the same dish"

Pros: "The crew was amazing and extremely helpful!"
Cons: "The food could have been better"

Pros: "Crew was very friendly and seat in KQ is super comfortable in Business."

Pros: "Excellent service"

Pros: "The crew was very helpful in all respects."
Cons: "Not getting everyone standing in line to board one hour and 10 minutes before scheduled departure."

Pros: "The cue lines per zone are a brilliant idea!"
Cons: "An explanation to passengers as to why there was a backup between the gate and the plane."

Pros: "The crew was efficient and friendly. The plane took off on time and landed on time."
Cons: "Boarding was slow and tedious. People still crowd around the boarding area despite there being row for the zones. Why they don't board from back to front is beyond me. The food was mediocre at best."

Pros: "Very little"
Cons: "Flight was very crowded. Flight crew kept bumping into my seat and never apologized"

Pros: "We were a little delayed, so I read my book. Not for long though as I was really tired after my flight from Los Angeles. I fell asleep right after take-off and didn't wake until we landed. Best way to fly :-)"
Cons: "Very little legroom for a 6'1" guy. Would have liked a bit more space, but I guess I was too tired to let it bug me."

Pros: "Flight was on time."
Cons: "Food could have been much better in comparison with other airlines."

Pros: "Everything. crew friendly and food/drinks the best"
Cons: "Nothing...all was wonderful"

Pros: "Service and crew are great"
Cons: "Seats"

Pros: "It was a nice plane and boarding was well organized."
Cons: "I was assigned a middle seat, if not for that I would have given a higher rating."

Pros: "The only thing that I like about the flight was that it was easy to boarding"
Cons: "The food was not heat correctly it was cold and I felt that the crew rush to give out the food. The seats are terrible, if the person in front of you reclines you won’t be able to see the screen if your watching a movie and you will see the top of the persons head."

Pros: "Great service, decent food"
Cons: "There was no WiFi on the plane"

Cons: "Flight was delayed, seated in the last row and non adjustable seating, so very little leg room. Dis-enbarkment was very slow."

Cons: "Leg space."

Pros: "Nothing."
Cons: "Everything. The crew seemed to skip over me and my husband multiple times. So we sat there with garbage the whole flight. My entertainment was broken and they had no solution but giving me $30 to use at the duty free shop the same day as the flighty. I paid extra for premium seating in an exit row and that was their idea of fair compensation. The crew ran out of vegetarian food so I didn’t eat anything but cold stale bread. The crew was non-existent most of the flight."

Pros: "Staff"
Cons: "We were 2h late"

Pros: ". Budget airline with no legroom or extras"
Cons: "See above. Nothing specific to like."

Cons: "I am not sure why this happened, but our daughter, travelling away from home for the first time, was targeted at every step of her journey. From the terminal in DCA to Cincinnati, to CDG. Delta/Air France clearly singled her out. i am outraged! I have traveled many, many times and have sent hundreds of students on nearly the same trip -- and none have had as rough a time as she had. They will be hearing from me."

Pros: "The free glass of red wine when the plane finally took off."
Cons: "The flight was delayed. We were told that it was just a half an hour delay by the man that was informing us of the delay and then we were then told by a woman that it was going to be over an hour. We weren’t told any specifics of why the plane was delayed, other than: “ the engineers are looking at the issue now”. We received messages saying that the flight was cancelled but then we were told to ignore that. We were told that we would have an update every 10-15 minutes but by the time we had the next update was 1 hours later, we were told that the plane will depart at 15:50- which we did. But we also sat on the plane for an extra 2 hours or maybe even more (couldn’t bare watching the time at this point) because the man that was supposed to push the plane backwards in order to reverse the plane didn’t turn up so we then had to wait for all of the other planes to take off before we could. Eventually the plane set off at 18:20 and I got in France 19:30-20:00 ish?"

Pros: "It was a wonderful flight and service . Hospitality and welcoming."
Cons: "Nothing everything was amazing ."

Pros: "Ground crew at CDG was helpful to file a claim for the lost luggage."
Cons: "Ground crew at MXP Was inexperienced. She called every one in my flight to form a new line and it was immediately total chaos. And then they lost one of our luggages!"

Pros: "Crew was very nice and the plane was clean and comfortable"
Cons: "Worse food I ever had on a flight ( a small bowl of lentils and some bread) Movie selection was poor, although not a big deal"

Pros: "Service was great, flight was on time and I really enjoyed everything"
Cons: "Little turbulence but overall it comes as usual so it was worth the flight"

Pros: "The airbus 380 was great and the staff very nice"
Cons: "Too mych bad smells after a few hours"

Pros: "Punctual, great food in Premium Economy, friendly crew."
Cons: "Took over 75 minutes (after arrival) for baggage to arrive on the carousel. Boarding area did not have well-defined lanes for different groups."

Pros: "Good cabin, but very conjugated :|"
Cons: "Too much of hassle checking in as the airlines partners with a couple of other airlines like Jet Airways, WestJet & Aircanada. The food was just okay and the cabin crew refused to serve extra butter. When you are serving extra bread, make sure you serve the butter as well. How could someone eat bread by itself?"

Pros: "The crew was good and very good pilot's"
Cons: "No leg room between seats"

Pros: "The price 50€ cheaper than the other operators. Quick flight. Kind crew."
Cons: "Lack organisation for checking. No difference if you have done the checking online. No breakfast on a 7am flight though included in the price."

Pros: "1) USB charger and electric outlet 2) Availability of 2-across economy seats (for a price) 3) Vegetarian dinner option available and not too bad 4) Flight arrived on-time"
Cons: "1) No on-board wifi 2) Not much seating room - very thin 3) 45 minutes late taking off"

Pros: "Boarding sevece was very nice and helpful Thanks so much"

Pros: "Punctuallity"
Cons: "Bording far away, got my cabin luggage and everyone elses into the cellar because ¨it didn´t fit in the plane¨. There was plenty of room, I had breakable stuff in my luggage, didn´t get the chance to choose. No entertainment AT ALL. Confort: no leg space at all. Not an AirFrance plane, subcontracted. Lousy food."

Pros: "Other crew members were very polite to us, in particular a younger tall woman."
Cons: "2 crew members, one named Terri were quite rude and short with us. I even heard her say she was ready to get off the flight. She also asked everyone around me if they liked their flight but did not ask me. She basically threw my coffee condiments at me and dismissed my concerns about the food. I was unsure if the fruit was expired and she quickly dismissed my question without any real explanation."

Cons: "Delay over an hour"

Pros: "It was as expected."
Cons: "Boarding was a bit tedious because we had to first board a bus to take us to the airplane."

Cons: "Rude check in lady who said I needed to check bag (but didn’t. Loads of space)"

Pros: "Crew was friendly, food was good"
Cons: "Entertainment was broken in one of our seats, the seats were not comfortable"

Pros: "The seats were comfortable"
Cons: "Everything was ok"

Pros: "Nothing, total stress making us re-check our baggage"
Cons: "British AIrways could have checked our bags through from Denver to Paris....after all it was British Airways to British Airways, but they made us check only to London, retrieve bags carry them to another terminal recheck them for what Simon the BA ticket writer was nothing but pure error by British"

Pros: "As always no issues at all, I reserved my seats early to get extra leg room which is always great. Fast boarding and a quick flight, having been on a long haul flight a few hours before I needed this to get home."

Pros: "The departures and arrivals were on time."

Cons: "Our flight was delayed causing us to take a red eye, missing our connection,long layover, missed our hotel for the night, thripled our time in transit. The worst travel experience I have had."

Pros: "Easy boarding, on-time departure, clean aircraft, friendly crew, decent food, free drinks."

Pros: "The crew was very friendly. Lots of movie options. I got a voucher due to the delay."
Cons: "The delay was a bit of a bummer and it would have been nice to be compensated with more than a voucher that couldn't be used in LHR because it was in USD. I also would have liked to been told they were still planning on serving dinner despite the midnight departure; I fell asleep because they turned off the cabin lights and I assumed the meals had shifted, but instead I missed out of my dinner. Lastly, I am quite petite and still struggled with legroom."

Pros: "Crew was friendly and helpful, food was ok."
Cons: "The flight was delayed by roughly 5 hours, causing us to miss our connection and have to wait for the next flight. We missed a half day in Rome and instead spent over 8 hours waiting in airports. The seats were also terribly worn and uncomfortable."

Pros: "Orderly boarding and disembarkation."
Cons: "This airline is one of the worst in Europe, for the simple reason of putting short-term profits ahead of decent treatment of the customer. My flight across the Atlantic was 4 hours late, and BA refused to put me on the next available to Prague, even though the lateness forced me to miss the BA flight I have been booked on. Their reason referred to a technicality in the booking procedure, but actually BA has put in place "policies" aimed at their financial advantage, over and above reasonable treatment of the customer. BA's refusal to rebook me cost me a lot of inconvenience (3 hours on the phone, for one thing) plus about $150 (I am taking another route to Prague); BA was then able to sell both my original seat and an extra seat on the next flight from Heathrow to Prague. I will never fly BA again in my life if I can help it."

Pros: "On board service and amenities"
Cons: "Kayak customer service"

Pros: "I like to fly BA because the crews ( and I assume the maintenance) are top notch"
Cons: "Tired old 747. Needs an upgrade. Packed in like sardines on an old plane that shows it age. Should have flown Norwegian. Major delay caused me to miss my connections though the BA staff were all over it."

Pros: "I arrived safe and sound"
Cons: "Even though I purchased an exit row seat we were packed in like sardines. I know airlines have to make money but that flight was ridiculous. also, the plane was way too warm for much of the flight. Not sure if there was a problem with the air but for these prices...fix it please."

Pros: "Efficiency"

Pros: "They were extremely accommodating."
Cons: "N/A"

Pros: "Quick"
Cons: "Nothing. The flight was quick and boarding was easy"

Pros: "it was very clean on a board."
Cons: "even water for money"

Pros: "The seat was comfortable and featured the good headrests."

Cons: "Plane was honestly very dirty. There was a ton of crumbs and gross stuff in th seat back pocket. Which I did not even use because I didn't want any of my things to touch.

Pros: "Fligth attendants of British, Iberia provided excellent and friendly service. Some of London British Airways desk and gates officcers, gave me really poor service."
Cons: "My flight to London was pretty good,. Service was excellent.. But not my transfer to Madrid , I lost my conecttion. On London airport, I was sent back for the gate because I showed up early and they ask me to take care of the screen and wait for the gate #, when they showed the # , I went to the gate and was told my flight had left an hour ago and sent me back walking . I was wearing an orthopedic shoe, due to a toe fracture and i had to walk again all this long distance back to the terminal.!! British airway gave another flight and had to pay $279 dlls for a ticket to Madrid.2 hrs later. My flight was by Iberia and the service. was excelent. I wonder if the insurance , I bought initially will cover something of the $ 279 dlls ticket ? Fligth back to EUA was by AA and service was excellent"

Cons: "The seats on these flights are poor. As well as being narrow, there are bars on either side that dig in to your sides. My ongoing one hour domestic flight had more comfortable seats. Fod choice poor. Chicken Curry or Cheese/Tomato Lasagna. If I want a vegetarian meal I'll order one beforehand. Give me two meat options. This isn't the first time I've noticed this.

Cons: "The staff was awesome"

Pros: "Wine with dinner."
Cons: "No tv for 9hr flight. Breakfast was awful."

Cons: "We purchased upgrades to an exit row seat because my knee locks up when cooped up for that long.

Cons: "You were out of earphones"

Pros: "We were allowed to board early with my father, who is disabled."

Phily to Prg - Crappy old plane that should not be flying over seas anymore. Applies to both flights unless specified."

Pros: "On time. Efficient boarding."

Cons: "Sitting on the runway after landing because the gate is occupied."

Pros: "No surveys"
Cons: "No surveys"

Pros: "El problema es que el vuelo estaba sobrevendido y han cerrado las puertas antes con lo cual me he quedado abajo sin pode abordar. En el aeropuerto de Denver habia solo dos personas en el securty check por lo cual la demora fue involuntaria en mi caso. Cuando estoy haciendo la fila para ingresar al avion (esyando en la misma cola antes de ingresar) me informanque no podre embarcar..(claro ya habia designado mi billete a otras personas. pesima atencion y pesimna experiencia con los empleados de ese vuelo. Denver a Miami"

Pros: "The Denver airport is beautiful"
Cons: "I will never fly AA again - see below"
