AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

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.

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

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!

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

The ladies are great seats should be a little bigger!

Couple of hours delayed, we had to re-booked our Shinkansen reservation twice. United Aiines need to improve their time!

The staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.

It was good. The crew was efficient, food was good

Seats were extremely cramped even for economy. Food was atrocious. Crew was fine but no follow up, additional drinks offered etc. For a 14 hour flight I expected more.

Boarding was good. Inflight service was good. Alcoholic drinks could have been served free.

Suite lounge in Honolulu is the best lounge in Honolulu. I love the huge bathrooms in ANA first Class on the A380 Honu plane. Japanese meal was outstanding and service was amazing. Everything was just excellent. Can’t wait to fly again

Their was $200 charge for 2nd luggage, airplane very new and flight smooth. Flight time seem faster then Asian stoping Korea then china.

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

Really hard landing... as in slammed into the runway then hit the brakes really hard ...

Putting people that close to the bathroom, where you have to look into the bathroom as people are exiting and entering was not great and the smell was also not great. I know the airlines are desperate for more chairs, but that seat is a crime.

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

one staffer was frustrated (it happen); the flight was late and the pilot mentioned they'll make amend but the snacks were the same, other than that the aircraft was clean and everything went smooth, no complaints

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

No seat back entertainment. And app had a hard time getting entertainment loaded.

ticket agent lady wás very helpful , she arranged wheel chair for my elderly mother

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

It was amazing with great service. But the seating could have been better if there was ample arm rest areas

Great food selection in lounge. Excellent bartender, friendly staff. Good service on the plane.

Check in process was excellent. Lounge needs improvement. Food not palatable and no good choices.

I like the pleasantness of how courteous and friendly and helpful everyone is

My luggages were lost and the service attendant was extremely unprofessional. Despite presenting my luggage claim slips, the attendant stated she had “no record” of my bags and made no meaningful effort to assist. When I explained that the luggage contained our family’s complete scuba diving equipment, her response was dismissive, stating that she “didn’t care.” While lost luggage is frustrating on its own, the lack of professionalism and lack of empathy significantly worsened the situation.

It was never explained why the departure flight was canceled and delayed for 1.5 hours. It would have been nice to stick with the original itinerary.

Flight was good took off on time arrived early. Crew was awesome and did a great job. Very helpful and courteous. Bags arrived super fast with no hassles. Great flight!!!!!!

Many movies do not have captions, which would have been helpful when you have to live with the flight engine noise.

Everything was fantastic!!!! I can’t wait to fly home 😃!!!!!

Flight was really good, considering the semi bad weather in MNL. Food was great. Crew kept offering throughout the flight. Wifi signal was intermittent though.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

It was good that our flight left early. It was a nice smooth flight and landing.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

It was a problem because there was a delay where we sat before taking off from newark,then when landed in Toronto we sat on tarmac and they wouldn't let us out for a long period of time. When we finally were released to the airport in Toronto the attendant scanned our boarding pass that we were here for our connection to Brazil. We ran all the way to the gate and they said at the gate the door is shut so we can not let you on the plane. We explained that we were checked in by the attendant when we arrived at Toronto airport to go to Brazil and they should not have shut the door. We were ignored at the gate

Flight home was delayed multiple times, did not get home until 2am

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)
