The crew was incredible. The pilots were so fantastic. The smoothest landing I’ve ever experienced.

The crew was incredible. The pilots were so fantastic. The smoothest landing I’ve ever experienced.

The flight attendants are always fantastic. My only issue – and it was on my Haneda to Vancouver flight – same as my Vancouver to Osaka flight – I had a confirmed special meal and they had no record of it on board. I tried to confirm it with the gate agent in Fukuoka, where I initiated the day, because of the mess up a month ago, and she said that they can't confirm special meals. I'd have to see when I got on board.

Great transfer of luggage from my flight with Osaka to Tokyo then Tokyo to final destination in Chicago

Great experienced staff and very pleasant compared to some other international airlines

Flight was good and comfortable, even for long haul economy. No complaints.

Check in was fast, lounge was good. Special section for ANA passengers in the Plaza Premium lounge. Boarding was organized and quick. Crew was very nice. They ran out of the Japanese meal so they asked me to switch to the international meal. Beef was room temperature and not hot. It tasted ok. Japanese meal was served hot. Movies were not great. Chair was very old and recline was not good. TV monitor was very old and not HD. Plane layout in business was 2-2-2. Should switch to the 1-2-1 layout for more privacy. Overall flight was average to good. Service was good but hard product should be updated to compete against much nicer Taiwanese airlines.

They lost my luggage on the inbound flight and then lost it again on this flight. I called online travel agent to change earlier flight to get a longer layover in Vancouver but ANA denied it

Suite lounge in Honolulu is very exclusive and boarding from the lounge into the plane is unique. First suites were huge and comfortable. Japanese meal is like a high end omakase meal. All the staff were very kind and provided sophisticated service. Fast Track upon landing was appreciated but not needed this time because immigration was so empty and easy.

I like the service very much. The food just okay but maybe different culture who like, who don't like.

Everything was excellent. Only the fish entree in the Japanese meal was overcooked and quite dry but everything else was great

It was okay, short flight so nothing much to comment.

The crew was nice, the food could be better, and at least 2 bathroom stalls were out of service.

The crew was attentive and provided everything I needed. The food in business class was excellent.

Good experience for economy transpacific. Reasonable comfortable seats. Food was not as good as I expected or had on other prior transpacific flights but likely attribute that to rising cost of supplies. Staff is courteous. Overall, very good.

Good the crew was nice very kind and very helpful

The original email I received and flight that I paid for was for Japan Airlines. Since JAL is a partner with American, I ended up on an American Airlines plane. This would not be a problem, except that JAL allows 2 check in bags for free and American only allows 1. A $100.00 unexpected expense was very disturbing, especially since I will have to pay it again on my way home. I feel like it was a bait and switch. I never would have chosen American Airlines if I had known that I would have to pay $200.00 in baggage fees, above and beyond my airfare. Secondly, the check in counter representative did not realize that I had TSA pre-check, so I had to return to the check-in desk on a different floor to get a new boarding pass. The AA representative helping at the check-in kiosks was very helpful, kind, polite, and professional when I returned for the new boarding pass. Thirdly, the crew was not as friendly as I have experienced on other airlines. Their tone when speaking to other passengers was not always polite. The food was better than I expected. However, I am used to having a station where one can serve themselves water, juice or grab a snack. That was not the case on this flight. Truly makes me think twice about booking with American Airlines. I am very disappointed.

Crews are rude and short. Example: after my drink and was ready to prep my bed to rest. I tried to give my empty glasses to the steward while she was playing her card game on her iPad. The steward told me to take the glass back to my table instead of taking the glass out of my hand. Compare Japanese steward it’s like heaven and hell.

I felt that the customer service improved compared to a several years ago.

I traveled business class from Lax to Narita flight Jl61. The crew was attentive and polite. Food was good quality and service was as it should be. Narita to Bengaluru Jl753was another story in business class. The cabin was darkened for the 9hr:30min flight, food was mediocre, service was below standard and crew can't speak English to save their lives. When you ask for noodles soup from Ala carte they gave cup of noodles while Lax to Narita i was served the best Ramen noodles in a big bowl. Why the disparity on this leg of the journey.....or is it because there were mostly Indian passengers and it really did not matter to Jal to bother as its a poor country and Indians refrain from speaking up? A good airline but differentiation like this brings their reputation and business down.

Japan Airlines was excellent as usual once on the plane. Cabin crew was wonderful as usual. Boarding was solid on the Honolulu leg. For Thai Airways the boarding was less organized. I was in an earlier group but they weren’t clear with the numbers or instructions. Flight crew from Japan to Thailand was very good.

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

First, Delta needs more flights to/from Miami. Second, a 1000pm leaving at 1230pm is unacceptable from their biggest airport world hub. Another aircraft could have been used such as the aircraft scheduled to be used in the morning for that exact same route. Yes, I did get me there but the lack of sleep the next day didn't help me enjoy my entire trip since I was busy with activities during the weekend. This can be and is expected from Spirit (going bankrupt) and Frontier (despite they're nickel and dimers). But from Delta's World Hub? That's totally unacceptable!

This flight was straightforward and without difficulty. Service was OK, but I continue to be underwhelmed by level of attention given to Sky Priority passengers.

It would’ve been nice for all that money to have a more substantial snack for free. I remember once upon a time getting a very nice turkey sandwich with Swiss cheese on whole wheat bread for no charge along with a drink. I guess those days are gone. it’s a little insulting being given a cookie or a bag of baked chips Going forward I’ll just bring my own.

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

The movies offered were great. Staff were very pleasant and very efficient.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Flight and crew were great. United didn't inform crew of immigration process which was disappointing!

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.

from SFO-> FRA flight, AVML meal was significantly less compared to regular meal, especially no Desert, no Bread, no sides.

This flight with a lot empty place , and I have more room, feeling comfortable.

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

The flight was delayed an hour, but not because of Air Canada. The crew was polite, professional, and competent. The food was above average for Air Canada, but just fine. The stand out for me in the 10 hour flight was the entertainment package. The best of any airline I’ve experienced so far. Looking forward to my return flight to finish some more of the shows I was watching.

Very good!👍!especially the typhoon coming, the speaking Chinese language service is excellent 👍!

Not to out myself as both a child at heart and kind of a terrible person, but the Pokémon safety video was the first time I watched an airplane safety video in like a decade. It was ADORABLE!! A great way to encourage attention from young and old alike.

I had a good experience. I liked being informed about the status of my luggage

Seamless! Long but the seat back entertainment kept us all busy the whole time! Meals were excellent! Crew fantastic! Very attentive!

The whole experience what excellent, from Anjou at the ticket counter to the attendants on the flight. Although it was an older plane, it was a very good flight. One of the best flights I have had on Air Canada!
