I show up for new departure time. Plane left six minutes earlier. First thanks for the bad information. Second thanks for not paging me. Third I don't care when the plane is supposed to leave. Just tell me what time to be at the gate so I can stand around after an international flight. Oh and if a flight attendee to squawk rudely at a paying customer when we do land, why I'd just have to ask myself AGAIN ... why do I fly United?"

Pros: "Best service ever provided by an airline"

Cons: "It wasn't such a bad experience for me but the plane did have a mechanical failure and the part was not in stock in Cambodia so had to be flown in. That resulted in a 24 hour delay. The ANA staff were excellent and did take care of us well."

Pros: "Friendly staff"
Cons: "When I went to counter to get my seat assignment I was offered 25,000 yen to take a later flight because mine was overbooked. I agreed and began notifying my transportation at my final destination when I was told nevermind, space was no longer needed. This was aggrevating."

Pros: "Very comfortable and nice lighting. Not too bright"
Cons: "The overhead light is too far up and when I turn on the light it's lightning up more than just my seat. Other people beside me are sleeping and it's too bright to turn on the light."

Cons: "Food"

Cons: "Connecting flight in Incheon Airport delayed again, 4th consecutive time this has happened on this particular flight. I think this is done intentionally so airline can combine it with the next flight that departs 50 minutes later based on amount of bookings on each flight."

Pros: "I liked everything. The crew was nice, there was leg room and if people wanted they could watch a movie. There was a nice small meal even though it was only an hour flight."
Cons: "Well, I'm not exactly sure. I understand why there were many different languages for the announcements. English, Korean and Japanese. Even though that stops what you're doing on the screen, it can't really be helped, unless they know which language each person prefers in each seat and programs the message to only play in that language for each individual seat."

Pros: "Exellent food service and comfort Will use Asiana in my future travels Had my best travel experience in years"

Pros: "The food is better than United, and the flight attendants were nice and professional."
Cons: "The seats were so narrow. When a person in front of you pushes back their seat your space gets ridiculously small...same problem with my flight from LAX to Incheon... It looks like that the aircrafts for this 10+ hr flight are older (smaller seat space) than the ones used for a 1-1/2 hr flight between Incheon and Osaka. Also the terminal at LAX is so far away from Tom Bradley main building that we needed to take a bus and had to wait about an hour until we finally got our suitcases."

Pros: "The flight got attendants were polite."
Cons: "The food was not so good as expected, to my surprise and disappointment. The seats were even narrower than my next connecting 2hr-flight from Incheon to Osaka... Also the flight attendants spoke only in Korean when walking down the aisles offering coffee, tea, etc. When I fly on other Asian airlines (Singaporean, Japan Airlines, All Nippon) everything is bilingual so it is easy to understand what is being offered or asked."

Pros: "Cabin, seat, and aircraft comfortable but not at all luxurious."
Cons: "Service was really bad, the toilets were filthy; in this regard probably the worst business class experience in recent years."

Cons: "It was cancelled. There was no proactive communication from Kayak or Asiana about the situation. We had to cancel and rebook ourselves."

Pros: "I enjoyed the USB charger available at my seat."

Cons: "It was very hot in the cabin. We were told that it was airline policy to keep the cabin that temperature. There is no way to adjust the temperature yourself. Also the chicken entrees should be avoided. If given the option chose the Korean meal."

Pros: "Cleanliness, friendliness and calm flight. Food selection in Economy was limited but quality of Korean offerings was good."
Cons: "Some restrooms were not supplied properly. Would have appreciated hot towel or other refreshment before landing after 12 hour flight."

Pros: "The crew was very kind and helpful. They always had a smile. The food was delicious too."

Pros: "The leg room and comfort of the seat were noticeably different from other airlines. I enjoyed this flight on the 777 much better than my return flight on an A330."

The airline managed to give my child and me seats next to each other after helping me rearrange my flight schedule. We were in an A380. It was a packed flight. The crew was efficient, attentive, and calm. Asiana Airline strives to be a service-oriented airline, and it was demonstrated on this flight."
Cons: "Communication is not always clear especially in-flight communication, more likely a language barrier that can be improved. Wondering if a ticker board would be helpful."

Pros: "Easy to switch flights"

Pros: "They were very nice! Always a smile, even after 10 hours with us!"
Cons: "Final snack was a ricotta pepper sandwich - which was kind of a weird choice. Kitkat was of course delicious. Beef stew for lunch was fine. but my meal come out with frost on it, so the salad was freezer burned and my dressing was unable to pour being frozen! no veggies for me! :)"

San Francisco airport horrible. No one gave us any information. They didnt know wfere is what. No one helped us."

Cons: "you cancled my return ticket when I got off the plane in Frankfurt and did not contiue to Geneva.."

Cons: "I propose to keep on board the plane some bright and interesting toys for calming the children who, for almost the entire 10-hour flight, cry and do not give rest to all the passengers. I understand that parents should have worried about this. But if the parents can not do anything with their child, the new toys could help calm the child, and not turn a long flight into torture for other passengers and crew."

Cons: "The seating was poor. The armrest did not go up even so I and another passenger tried hard. I then had to climb over it to be able to get to the washroom at 86 that was not the easiest and again it should not happen regardless. Otherwise I was treated well.I was a wheel chair passenger for medical reason. Thanks Helen"

Pros: "Same"
Cons: "Same"

Cons: "3rd flight in two weeks suck sitting next to a morbidly obese person. They should be forced to purchase two seats."

Cons: "the drink service came through pretty late in the flight. i asked for hot tea. a few minutes later i was provided with extremely hot tea. about 10 minutes later it was a temperature i could tolerate drinking. about 1/3 through the drink i was required to throw away my drink because we were preparing for landing. i understand that, fine. bad timing. it’s just a drink. what was unsatisfactory is that the attendant rudely commented “you have to give us your drink. it’s not that long of a flight.” the comment made me feel like i had done something wrong even though i had just been drinking my tea as soon as it was at a drinkable temperature. i was not impressed with the attendant. also, there weren’t any biscotti cookies."

Pros: "Pilots that did show up were pleasant and made the best of the situation."
Cons: "No scheduled pilots for this flight. Pilots that did arrive had their schedule rearranged---they showed up to work thinking they were flying to Seattle. They were asked to step in to fly to Denver instead---20 minutes after our scheduled takeoff time; not horribly late, but seemingly disorganized, which leads to all kinds of thoughts about AA overall competence."

Cons: "Food"

Cons: "The gates closed early and I missed this flight! Horrible service, never flying American again."

Pros: "The first leg had awesome pasta.Then, on the 2nd leg, Philly to Denver, they had a "pay for meal" option for turkey with Chutney sandwich - again, delicious. I should add that the service was very good as well."

Cons: "Everything. Had to sleep overnight in airport and was late coming home."

Pros: "Staff was great!"
Cons: "Seats were really uncomfortable up and reclined. Overhead baggage was full by the time I boarded and there was no enforcement of the carry-on baggage sizes... This needs to be addressed and contributed to our lack of comfort, noting this was the last leg of an 18 hour journey. My body still hurts today after a good nights sleep."

Cons: "No tvs!!"

Pros: "We were able to get to Denver"
Cons: "Jammed in like sardines, rude flight staff, extremely hot aircraft for November"

Cons: "Unexplained delay in leaving but only arrived about 10 min later than scheduled. Took an hour from pulling into the gate for bags to arrive though which caused me to miss my shuttle. Never had to wait more than 15 min for any other airline at DIA."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Pros: "The departure time. This left enough time to get to the airport and go through security without rushing!"
Cons: "Sitting in the middle Paying for luggage ( I wish Southwest flew out of ORD)"

Pros: "A free airline ticket!!"
Cons: "I did not like the fact that American Airlines cancelled my 17 Yr old neice's flight from Dallas to Denver over a thing called "timed-out". And had her sleep in a room with a cott instead of a hotel room. And the fact that we as customers pay good money for tickets only to be subject to the airlines way of business. It is absolutely unacceptable!"

Cons: "Wish the seats were a bit more comfortable on frontier. And had to pay for carry ons. Will never ride frontier again."

Pros: "The flights were on time and without incident."
Cons: "I did not get an email to check in, what is up with that! I bought a 14" roller bag to fit under any seat. However it does not fit under all of your aisle seats. Can you indicate seats with less space on your maps. I bought the bag so I wouldn't have to lift it up. Leg space is better on Delta and under seat room also."

Cons: "Little more time between flights would be nice"

Pros: "New illy coffee is really good"

Pros: "New plane"
Cons: "The way you bord the plane"

Pros: "Convenient, cheap, best route"
Cons: "Incredibly uncomfortable seats on the express jets - we joked that we need to bring stadium cushions next time. For a full day of traveling, I would consider a more expensive route with another airline than tolerating the hard seating they offer."

Cons: "The airplane was freezing, and I'm 23 years old and very used to flying."

Pros: "All went well. Pleasant attendants."

Pros: "It was inexpensive"

Pros: "that they warned me the plane was extra small and checked my carry-on at the gate for free."
Cons: "that they didn't really advertise how small of a plane I would be flying. I guess you're supposed to research every plane before purchasing tickets now."

Pros: "Time and confort"

Pros: "Agents checking baggage were unbelievably slow. Good thing there wasn't a long line."
