The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

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!

This flight was a superior flight in all regards. Extremely pleasant experience.

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

Very comfortab flight. The flight crew and service was terrific. The food was average at best.

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

I wouldn’t know, I tried to contact you days before to reschedule my flight back to Okinawa but you left me on hold for 2 hours. I tried calling multiple times and not once did you pick up. I had to spend 2000 dollars on a one way ticket back to Okinawa because I couldn’t get ahold of you guys to change my flight.

I fell asleep, and the crew kindly left some snacks for me

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

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

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.

great experience - staff were kind and attentive and food was excellent. very comfortable flight that felt much shorter than 14 hours.

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.

Food is basically Sun Chips, cookies or Cheezits. I had an exit row seat so I had plenty of room. The crew was very nice and efficient. Pilot kept us informed. Pretty good flight.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

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.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

I like flying first class, and United has a nice one

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check-in, boarding and the flight from Phoenix to Houston was quick and easy. The flight from Houston to Shreveport was delayed 5 hours. It was frustrating but I think United handled it the best they could.

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.
