Customer service in Hanoi needs work, outside of that, everything was good.

Premium economy seats that I paid extra are not worthed.there was not much difference from the regular economy seats yet I paid alot more for it Disappointed

It did not feel like a luxury airline. We had booked premium economy and opted for AVML meals. This was one of the worst meal in any of the flights and I’m a frequent flyer. No great snack options were available. Drink selection was limited to wine and beer. On a long flight, you need a variety of food which was unfortunately not available. The seats were just OK and the foot rest are not comfortable.. Airline staff for courteous Audio and video section is extremely limited

Hostesses were very nice I am disappointed that I paid extra 900$for premium economy which wasn't much upgraded from regular economy, I have wasted my money on this trip 😫

amazing and great food. everything was smooth from start to finished

love this boutique luxury airline. crew was nice and attentive. Lounge is too small , i think they should have more area for relaxing and lounging not just to sit and eat .. feels like a cafeteria more than a lounge. overall i enjoy it. food on the plane LAX to Teipei should inprove a bit. no flavor and more drinks pls

The overall experience with STARLUX was phenomenal. One of the best highlights for me was the smooth landing in LA(smoothest landing I’ve experienced ever) and the attentiveness of all your staff from check-in to boarding. Also, flight left and landed between airports on time. I highly recommend Starlux to my family and friends and I’m excited to fly with you again.

We are scare because almost missing the fligh from Seattle to San Diego ! Starlux not have enough members for servicing with wheel chairs? We almost left behind , so we must walking !?

We are on economy premium but they put us in economy seating? Asking why the fligh supports said : If you not happy you can claim for refund?

Everything is smooth. Very good. Except flight arrived SFO 30min late.

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.

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

As usual the flight from AUS in Austin to SFO was late because they didn’t have adequate staffing to board the plane on time creating a 1 hour delay, which resulted in me missing my flight to Osaka due to a missed connection. When I got to the gate 10 minutes late after landing exactly the time the connecting flight was taking off, I saw my flight to Osaka sitting at the gate and that gates had closed. I attempted to contact United Via chat on the United App and was given the runaround and passed between 2 separate “agents” who after saying they could rebook me, told me I needed to go to ANA even though they’re partners and all of my ticketing was through United. After going to ANA’s gate at SFO to try and get help I was told I would need to leave and go to United’s ticket counter in order to get help. The ANA agents said that it was United’s issue. An hour after running to try to make my flight I got to the United counter. I showed the agent my itinerary and she helped as much as she could. I was booked on a flight that would occur 13 hours after my original flight to Osaka and given $45 in vouchers which doesn’t cover much at SFO. I had also spent 30000 miles with United to get an upgrade with more legroom. And that was not refunded to this point. Ultimately I lost 1 whole day of vacation in with my wife and kids and, the 30000 airline miles and I’m out the money and time I spent. In these situations United and their partners should go out of their way to communicate and accommodate but I was left to my own devices to find the right resources. The only option was to fly to Seoul 12 hours and take a connecting flight to Osaka: I am a United Skyniles member and would not recommend booking a flight with them unless you thoroughly understand the routes as it is likely you will be left to your own devices to resolve the situation.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

Staff at gate and crew on plane efficient and friendly.

I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

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

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

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.

I am thankful that I was able to fly using Asiana

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.

Better screens, it would have been nice to have more comfortable seats.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

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.
