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.

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

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

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.

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

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

Love flying Asiana. Been using it for over a decade now.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

I like the food, the crew and everything.!!! Except for the delay in our flight.

Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️

My favorite airline to fly across the Pacific. The Business class lounge is fantastic, the wonderful flight attendants are helpful and professional. Great comfort while flying.

I recently had the pleasure of flying with Asiana Airlines, and I can confidently say it was an outstanding experience. From the moment I checked in, the staff demonstrated exceptional professionalism and warmth. The boarding process was seamless and well-organized, ensuring a stress-free start to my journey. Onboard, the flight attendants were attentive, courteous, and went above and beyond to cater to passengers' needs. The seats were comfortable, with ample legroom, and the in-flight entertainment options were diverse and up-to-date, making the flight enjoyable and relaxing. Additionally, the meals served were delicious and well-presented, reflecting a high standard of culinary quality. The airline's commitment to safety was evident throughout the flight, with clear announcements and a reassuring presence from the crew. Overall, Asiana Airlines provided a top-tier travel experience, and I would highly recommend them to anyone seeking comfort, quality service, and a memorable journey.

Very good flight. Crew was great. No issues and we even arrived early.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

There was a loud squeaky sound the whole time we were flying.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Complimentary light meal would be appreciated. But great flight crew service on all legs

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

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.

We were traveling as a family of 5 and they refused to seat us together. There were entire rows open, and my 13 year old daughter had to sit alone. Ridiculous!

The flight attendants went out of their way to help me align everything so I can catch my connection as soon as we landed

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

Real smooth and easy, Real good leg room in coach!

Plane was old, cabin was small, overhead bins were small, seats really uncomfortable, no seat-back entertainment

I had a disappointing experience at the San Diego airport with one of your gate agents. Despite being in Zone 4 and traveling with a standard carry-on bag that has never been an issue (30 flights in Q4 alone), the tall, blonde gentleman forced me to gate-check my bag. When I politely asked if we could verify the bag’s size, he became confrontational, even threatening to deny me boarding twice. His behavior appeared erratic and unprofessional, projecting a negative attitude onto passengers, as if he was going through something mentally. Notably, there was ample overhead space once all passengers had boarded. In contrast, the tall, older Asian agent handled the situation with professionalism and calmness, making a clear effort to de-escalate. As an avid traveler, this unnecessary inconvenience set a frustrating tone for my trip to Asia.

. Crew was professional and friendly. Food could have been hotter

Terrible. They cancelled our flight the night before. Please give me a call to discuss.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

Everything went smoothly and as expected. We were on time and one flight arrived early.
