Great level of comfort and highly professional and friendly flight crew. Keep up the great service.

It was amazing. Japan is lovely. I hope to go again. Thank you for everything.

My first issue is the lack of clarity with the airlines. I know that Japan airlines and American Airlines are partners, but I couldn’t figure out which airline I was flying with. I got the flight info for Japan airlines and ended up on American. After my Kayak booking (via Underpricer) I got a phone call to see if I wanted up choose a seat and pay for luggage fees. both American and Japan airlines offer 2 carryons and 2 regular luggage checked in at no additional fees to Tokyo. Having already done my research, I opted out on their “Offer” and just contacted the airline directly to pay for upgraded seats (Which were cheaper than the Underpricer deal) My top complaint was the flight delay from HND to LAX it wasn’t until I had already made my unchangable airport drop off car reservations , that I received 3 hour flight delay email. I was forced to be there 6 hours prior to the departure. They were kind enough to give us a limited restaurant food voucher- which was 1900 yen ( I saw Delta food vouchers were 2000 yen). My teen and I ate food court pizza. The flight arrived when expected, The food was mid on the flight. I slept and woke up about 1.5 hours to LAX. I had waffles ( which also contained 1 mushroom and 1 tomato in the same tray) and 3 small pieces of fruit. All went well, just remember to check on your 3rd party ticket companies. Some seem to be sneaky All in all it was a very long day, we made it back safe.

I have been flying with JAL a few times, crews service, food, overall comfort even with economy, I would rate it the top three airlines. None of any American carriers can provide such excellent service.

service was excellent. crew very polite, courteous, and good service especially to passengers like me who is a wheelchair passenger

First of all it’s an American Airline flight not JAL as advertised. Code share is deceiving. Seats are uncomfortable. Stewards in our section were not friendly, felt rude at times.

Lovely flight attendants comfort in Economy Premium. Very attentive and kind I would choose JAL again for sure!

Excellent overall, the staffs and amenities were delightful even using the outdated aircraft.

I enjoy flying American airlines. I tried to book American airline when I’m flying most places.

I enjoyed flying on Japan Airline. However, my flight from Osaka to Tokyo did not give us enough time to make my connecting flight. We missed our next flight due to the following: We were seated on row 24 which causes us to get off of plane late, having to go to the restroom, having to exit the airport and take a shuttle-bus from terminal one to terminal three, having to go through security and immigration. We were disappointed that we had to catch another flight

The flight was delayed. The staff made us wait in the room that is too small and it was crowded and with no seats available for waiting. They did not tell us why the delay occurred.

While boarding at PVG, there was a ticket checking at the gate, then there was another ticket checking at the bottom of the escalator, which created quite a dangerous congestion. Not sure which idiot made this absolutely unnecessary arrangement.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Plane was good. But food was bad and air host was so rude. I will never fly with China Eastern again

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

CTU-KMG-CNX with 1.5 hr connection at KMG. Doable but just barely bc immigration exit from China is at the last flight leg, here: KMG to CNX. We hauled out of the domestic terminal to reenter at the international departures (luggage checked thru to CNX thankfully). Immigration had only two agents, even though KMG gets a HUGE number of foreigners. It took forever for such a shot line. Then security also took a while, so I just just made the connection. Recommend if you exit China with domestic international transfer, plan for 2+ hrs to avoid a heart attack. Airline personnel don’t suffer if you miss the flight, you do. Plan accordingly.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers. A BIG ISSUE FOR NON-CHINESE PASSENGERS IS THE ABILITY TO CHECK IN ONLINE, by making so difficult or almost impossible there is no chance to get a seat assignment ahead of time then go to the airport and get what is left. THIS IS NOT a SKY TEAM modality.

The meals were not the greatest and lacking of appetite but everything else was spot on

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

The whole experience was excellent, O can say out from Miami the best airline to travel with for any European destination. Since the ground staff to the inflight crew attention was great, service on board 10 of 10. Finally the 380 is very confortable and nice to travel.

All crew except 1 were excellent. When I asked assistance with business class seat conversion to a bed (not being familiar as never used before but have numerous times with other airlines) crew member helped very reluctantly. I should have told her that business class seat conversion is totally different in each airline such as Delta, New Zealand Air and United. Sorry it was my 1st time with America Airlines. Now I know, I won't bother asking assistance in future.

I had a mixed experience on this flight. The plane itself was comfortable, the flight was smooth, and the entertainment selection was excellent with plenty of movie options. However, the service fell short. I had an entire row to myself and fell asleep with a blanket over me. A flight attendant, Karleigh, woke me up to see if I had my seatbelt on, which felt unnecessary given the situation. Meanwhile, trash sat uncollected on the tray at the end of the row and was never picked up. During the second meal service, no one woke me up, and when I used the call button multiple times, there was no response. I eventually had to walk to the back to ask for assistance. There was also a long stretch without snacks, and when I requested something savory, I was dropped off sweet options, which wasn’t ideal. Overall, while the flight itself was comfortable, the lack of attentiveness and responsiveness from the crew made the experience disappointing.

The seats in Premier Economy were very comfortable. The food was better than average. The way British Airways handled our seating was atrocious.

The flight attendant does not pay attention to my "call" button more than 3 times when I need a drink.

Flight delayed, connection was not at gate listed and so missed, staff were rude at Heathrow, phone tree stupid and difficult, took me 21 actual hours to reach my destination. Almost lost my hotel reservation after walking in a strange city alone after midnight because they would not put me up in a hotel at sfo or heathrow. I will never fly BA again and will tell all people and Instagram followers never to fly BA.

British Airays fails to enforce its own guidelines regarding carry on size limits. There were MANY passengers with full suitcases stuffing them into the overhead compartments leaving no space for others, like me, who adhere to the posted sizes. I had to put my carryone bag into my foot space, in additon to my carryon personal item, leaving me cramped for a seven hour flight. I was in physical pain, and I attribute this entirely to staff unwilling to enforce limits. The infotainment system was horrible. the touchscreens did dot work correctly, and there was no information on system operation. I am 77 years old, and a lifelong movie-goer. I recognized ONE movie (and not much better TV shows). It seems that BA saves royalty money by limiting its move and TV selection to absolute rubbish. The FlightAware program is the worst informationsystm I have ever seen, it is completely worthless. I pay attention to the safety briefings...in the event of an emergency, one is supposed to assume the "brace" position, except the seats are so close together, front to back, that it is not possible to assume the position without striking the seat in front of you. at age 77, and a lifelong traveler, this is the worst flight experience I have ever had, and I will never fly British Airways again

Overall ok. Best part has always been the sundae dessert.

I’ve never been on a trans-Atlantic (or Pacific) flight where the seats don’t recline—not even a little. I asked my seat mate when BA starting doing this and he said “Oh, a few years ago.” I couldn’t sleep, with my head falling forward waking me continuously, and came off the plane incredibly stiff. I booked a Premium Economy seat to get a more comfortable seat, which was worse than most basic Economy seats I’ve ever booked.

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!
