Cabin Crew was excellent. They took care of everything requested. Flight was good

I didn’t know that my connecting flight from Japan to Hawaii was at a different airport - arrived in Haneda (ticket said Tokyo but didn’t notice the airport name) and had to get my bags and go out of immigration and back in to go to Narita airport 2 hours away. Such a hassle and SOOO confusing and complicated. Check your airports IN ADVANCE and NEVER book if you have to change airports. 40+ years of flying and first time had this. Never again. ANA is great but booking agencies will sell you a connection that you have a good chance of missing - even under the best circumstances.

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

I was too late to get onto this flight. Kayak shouldn't let you book a connecting international to domestic flight when flying ANA. Your domestic flight could be in a different terminal and you won't make it because you have to go through immigration and customs.

United Airlines crew members do not know how to deal with emergency situation that caused our flight delay. For example, they should have asked the maintenance or seat belt repair personnel to come and fix the seat belt while they were looking for a volunteer to book another flight.

I always take ANA because of the great service and overall experience.

Tokyo Haneda to transport was so bad too short time . and find out way to the gate was so bad. I almost missed flight. because confused. They need more great way tell us how to get there details

Entertainment and food is best. I love to use ana for a lots japanese movies…. Food was best

The flights were on time and the cabin crew were very nice. The only downside was that the food was not good.

Good pilot and crew. No food or beverage on this flight Entertainment is via own device thru plane's wifi.

My plans changed and I tried to cancel or change the flight for credit but was giving the run around and denied . Not great

Excellent service, excellent food and beverage options, plenty of leg room

Checking in as an international flyer is a bit tedious

I was so hungry , from Boston to Tokyo, only 2 big food .

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.

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

The flight was comfortable and uneventful, which is what I desire

The entertainment screens were not working and there was no air condition the entire flight. Very uncomfortable.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

None of the airplane features were available during the flight.

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

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! 💗

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

The attendant on board was amazing. She should be doing business/first international long haul.

Although our flight was delayed the overall boarding process was very smooth and the crew was accommodating.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

A great experience with excellent service by the crew and attention in assisting the passengers.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

The food was terrible this time. Otherwise pleasant, quiet, on-time.

It was a pretty standard flight... until the almost hour and a half spent on the taxi way. I get that the weather has been poor but the delay had nothing to do with the weather and more to do with a plane with several issues tying up the gate. I get that that happens from time to time but this has been EVERY flight I've been on for the past 5 years and I fly 3 to 5 times a year. This isn't just United... it's American, it's Delta. It's an issue with the entire industry. I work for UPS and packages on a cargo plane get better service than people do these days. Anymore I HATE flying.
