There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

long flights are difficult but the crew and amenities made it a very good experience

Everything was great. Wifi was down,but that didn't matter to me.

The staff are very kind ,friendly and helpful .This is my first time flying with ANA and surely will fly again.

Hard to explain because we thought we were booking ANA airlines, not ANA operated via United, so we were disappointed, but for what it’s worth, everything went smooth and loved the movie selections. The food was okay, processed and full of preservatives, so vs what we were expecting with ANA it was different

The best best best flight experience I have ever had. And I fly A LOT. THANK YOU, ANA!!!

My wife and I liked almost everything about ANA except for the economy seat space and the cold breakfast (croissant which seemed to just come out of the fridge)

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

This was a large plane with an upper deck. It seems like business was upstairs. If it was a US airline then I would say I sat in economy plus, but I think it was just economy. Though since ANA would not allow me to choose seats for the price it may have been plus. Lots of movies to choose from, and good service.

This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.

There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

The economy seats are much indeed roomier. Meals needs improvement.

When comes to Taiwan airlines China airlines is the best rest are pure trash

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

United out of SFO is having issues with catering so none of our meals were loaded on the plane and no offer of compensation for our tickets purchased was offered.

Boarding seemed to be organized bedlam. For what ever reason, preboarding took longer than 20 minutes. Made the plane 20 minutes late taking off. Luckily we arrived on time. Flight crew seemed very friendly. Only slight turbulence.

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

Delay and keep changing gates. I have to run around from B to C then to E.

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

They hired a new catering company the same day of my flight. They botched the job by not delivering the right carts and after THREE HOURS waiting, the flight crew timed out (flight was 19 hours long and FAA rules state crew can’t work more than 14 hours long). So they CANCELED OUR FLIGHT!! Worst experience ever. Avoid UAL at all costs.

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

Not really their fault, but a 4.5 hour delay is pretty brutal

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

The layover was 6 PLUS hours and we were only given a $15.00 voucher. We missed our first activity in Quebec due to the delay.

Miserable staff as it was a late/delayed flight and crew wasn’t in the best spirits. Completely understood as neither was most of the passengers. Still unacceptable l.

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

It was a short flight, and no entertainment. That was not a problem for us, but there is no option for "not applicable". There was a bit of turbulence, so there was no food service.

the fact air Canada changed my flight from 850 PM to 815 AM with zero regard to the plans i made that last day, the cost i lost out on as things were non refundable amd shortening my first vacation in 7 years sickened me. when we purchase a service thats whats we expect. when we want to change the service we have to pay for that option but you do whatever you want . i called accessibility dept as i have a cpap and an implanted loop recorder first person said no problem just let security know you cant go thru scanners. then i got an email saying i had to fill out a fit to fly form . which again there was NO need to have that none. But that cost me money and time to have a doctor fill it out. then when i went to check in online i was declined i had to see a person at the airport instead. i couldnt get my boarding pass like everyone elseso here I was contacting air canada so I would have a easy travel experience and it ended up being a nightmare with more work for me, more cost and time. the flight itself was great the nightmare around it i will never subject myself to again. i tried to stick with supporting Canada but Air Canada was not worth supporting. very disappointed especially with a dept that is supposed to help disabled people not make an already challenging event not worth going thru at all.

Most courteous, helpful employees and all flights were on time.

All was good except for the seats, not very comfy.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.
