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."

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

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: "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!"

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

I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Pros: "Seat was comfortable, food was good."
Cons: "The woman seated next to me was the mother of one of the flight attendants. She had terrible body odor that nearly brought me to vomiting—and this was a 10 hour flight. She was also brought all kinds of amenities from the attendants from the 1st class cabin—not really appropriate."

Pros: "More leg room"

Pros: "Great service!"
Cons: "Breakfast and movie selection could have been better"

Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."

Cons: "It wasn't an issue on my flight since there were empty seats in my row, but I don't enjoy the spacing provided for personal items on the floor under the seat in front you. For four seats there are three sections; so, you can hope that someone doesn't need any space or else you have to decide how to awkwardly split it up."

Pros: "very professional cabin crew"
Cons: "The overhead bins are way too small, and they ran out of the vegetarian dinner option. There are no longer air controls for each seat, and the plane was quite cold."

Pros: "See above"
Cons: "See above"

Cons: "We were charged a rebooking fee by Lufthansa when customs searched luggage causing us to miss connecting flight"

One child had one on tye chair and I asked him if its suppose to be on the seat or given later on. He said it will be passed later and then with a patronizing manner he gave another head phone set and said: "I guess we havw an emergency". On the flight, every time he with the food and drinks he just stood there next to me talking over my head with the passenger begind me. Very uncomfortable, especially when it happens 6 or 7 times. When asking what drink we wanted ( the first time), i replied apple and orange juicewith no ice. He replied, with a patronizing manner "this it European company, not American company. Here we don't put ive if you do not ask for it".The incident that bother me the most is one that involved my kids also. My daughter (3 years old) was a bit scared of the flight, tired and did not want to sit on her chair. We tried to keek her on the chair buy she started crying laying down on the floor infront of our seats. Jorge the flight attendant saw her and told me to put her on the seat. Not in a manner I expect out of soneone in the service industry. I told him we are working on it and we will have her on the chair as soon as we can. When I said that he got irritated and a bit aggressive. For no reason the situation became hostile. The flight attendent on the other side (do not know his name). Can over and asked us what we needed amd if we need help. I told the other flight attendant we need 5 minutes and he said OK. After a few minutes she calmed down. Anotger passenger asked Jorge what beer it is and he replied, with contempt, " its German beer, its good"."

Cons: "Food"

Pros: "Good food, friendly service"
Cons: "More trash pickup; only one round of beverage service"

Cons: "At the check in they made me pay 50€ for my luggage. This is really upsetting because from Houston to Venice they didn't make me pay. Either the website wasn't transparent or the lady at the desk made a mistake. Very upsetting, one luggage should be included."

Pros: "Good flight, arriving well on time."

Pros: "Comfort was better than on the previous Dash-8. Food was OK."

Cons: "You are almost always late!"

Pros: "We were fed a nice pasta meal and offered drinks twice. They also gave a muffin for desert. The flight attendants were very nice and attentive with cheerful smiles. I wish every airline had service this good!"

Pros: "Comfortable seats. Warm plane with happy staff."

Pros: "good service"

Pros: "newer plane, good staff"
Cons: "need better and more food options, more often"

Cons: "Per usual, KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Strange choice of in-flight movies; no accounting for taste, I guess."

Pros: "Boarding/unboarding"
Cons: "Didn't allow my carry on. Said too big. Same bag was on earlier connecting flight on much smaller plane. Also on flight on Southwest week prior. But larger intercontinental flight wouldn't allow it."

Pros: "That we didn't crash"
Cons: "Being delayed and missing my connecting flight. No entertainment onboard (for hours and hours)."

Cons: "One of the senior stewardesses we're very rude. Whether it's her personal opinion or KLM's policy, it's unreasonable to think that a 3 years old child could or should hold her pipi over 20 minutes, while they slowly and inefficiently trying to give out food. Several parents were there with the request to let us through to the toilet with small children and she smiled in our face and said "no, we will finish first and than you can go". She might be not fit for the job anymore, but KLM can't afford this kind of treatment."

Pros: "The crew were really helpful since I am a short person in putting my luggage away in the overhead compartment and attentive to everyone's needs. I am a fussy eater and don't really like airplane food but the food was actually really nice. We was given plenty of snacks and drinks in between meals as well. There was plenty of programmes to choose from to keep me entertained."
Cons: "The seats in economy were a little too small for a 12 hour flight"

Pros: "Same as above"

Pros: "The cabin crew were fantastic and funny"
Cons: "Tiny seats"

Pros: "Quick (relatively) flight."
Cons: "Skinniest seat ever. Couldn't even lean back. I now have hunchback."

Pros: "Short layover connecting from US flight and luggage transferred ok to destination. Food option not great but at least they didn't charge for it unlike some other airlines. No entertainment but to be expected on such a short flight."

Pros: "Crew was friendly, food was good"

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: "The departures and arrivals were on time."

Pros: "Polite, friendly staff."

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: "BA crews are always great. Also excellent that they don’t have those annoying M&S menus on LCY flights. I don’t object to paying, but it just slows everything down."

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: "Crew was very attentive and food and drink good as on most flight to and from City Airport. Seats very comfortable compared to main fleet. City Flyer is still worth paying the extra which most flight by main fleet ex Heathrow or Gatwick are not."
Cons: "Flight was delayed and boarding not great as we were kept waiting in a hot bus outside the aircraft for 15 minutes"

Pros: "Comfortable short hop"

Cons: "Pointless priority boarding if you get all priority passengers to wait for the rest of the flight.."

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

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

Pros: "The seat was comfortable and featured the good headrests."
Cons: "Food was inedible so I left it. The sound on the movies was tinny making hearing difficult."

Pros: "Par from below the flight was great as always"
Cons: "CSD was rude and not nice to his fellow staff member in economy. Small delay but not a common thing"

Pros: "The plane wasn't full, so there was an empty seat in-between my aisle and their window, as well as open spots throughout the plane."

Pros: "Crew were exceptional in service friendliness and attentiveness."

Pros: "Food was delicious and out flight attendant was very helpful. Plane was quiet and the movie options were good."
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. The overhead lights were covered in dust. So make sure you have some some type of cleaning wipes with you!! I do understand that I was flying economy, but that doesn't mean nothing should be cleaned."

Cons: "For some reason we were boarded and ready to go and only then did they think to send for a de-icer. A 40 minute delay on a 1 hour flight. At the other end we then had to wait 20 mins to get off."

Pros: "food was good"
Cons: "IFE was not good the equipment is very old and selection is limited"

Pros: "Simple flight left later than expect but arrived earlier than scheduled. Leg room was plenty and not like other airline where you feel packed like sardines."
Cons: "Nothing so far just a shame my luggage was damaged."

Pros: "Flight"
Cons: "Boarding at Gate E46 was disorganised both in timing ans execution. We were told on checkin that boarding would be early and it was late, closer to the original estimated time and then the order of boarding, parents with kids, then ExecClub and Business, and then others was ignored..."

Pros: " Cons: "I was disappointed in the food. On my second flight that day my ticket said I would get a meal but I didn´t."

Pros: "Left and arrived on time! Comfortable aircraft"
Cons: "Nothing"

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. Is it cost cutting? Seems like it to me. Not impressed."

Pros: "When it got going, a pleasant flight."
Cons: "The delay was longer than the flight, although not necessarily BA's fault."

Pros: "Everyone was awesome"
Cons: "The staff was awesome"

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

Pros: "No turbulence!!!"

Pros: "Food good and very attentive and friendly Cabin crew Amanda made the flight a pleasure."

Pros: "No access to any lounge services. Food selection and quality significantly behind competitors. Does not just the price charged."

Pros: "Easy and quick boarding. Dinner tasty, but it is hard to cut a fillet steak without hitting the next passenger in the elbow"
Cons: "Only one check-in agent running all desks including bag drop - long wait. 19 year-old 747 had narrow seats in premium economy, uncomfortable and too much body contact with adjacent passengers. Outbound to SFO in an Airbus 380 had sparkling wine pre-take off, hot towels twice, this DEN-LHR flight only had juice or water on offer (crew said "don't serve that on this route") no hot towels, crew's objective seemed to be get around cabin in one go and leave Pax to it Breakfast was abysmal, soft-pretzel roll, no juice or water served, just indifferent coffee"

Pros: "On time, friendly crew and decent food. Price also good"
Cons: "20 year old plane with tiny entertainment screens. Old and uncomfortable seats, especially for a long flight. Can't believe we were at a remote parking position inbound and outbound at LHR..."
