Was not able to buy wifi on the plane given, not available for economy tickets. Was not clear when buying the ticket that this was the case.

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

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 😫

The food was amazing good especially for evonoply. The seats were comfy more then usually..crew was very nice and helpful.

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

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?

FLEW IN BUSINESS CLASS OVER NIGHT FLIGHT AIRLINE BOOKED A PARENT AND ONE YEAR OLD KID PARENT ALLOWED THE KID TO DISTURB EVERYONES SLEEP A terrible flight that was expensive I have 10 grand children I love kids But to be disturbed on a over night flight is in not what I paid for I hold the air line responsible Respectfully, Al Eaddy

The crew were professional and attentive. Blankets and pillows were on each seat which was appreciated. The food was served warm and had a balance of various nutritional options. As far as the monitor there were not enough English speaking choices and foreign shows did not offer English captions.

We really enjoyed our flight to Seattle. The food was great and service was attentive.

The crew are amazing. Very professional, polite, kind, and accommodating.

The crew was very professional and friendly. Although there was a water leak from panel above, the crew was trying to mitigate the consequence. We are happy with its service and the value offered. We will definitely take China Airlines again.

Well, we upgraded and on a 14 hour flight not sure how we would tolerate it otherwise. The upgrades are ridiculously expensive and even with empty seats even in first class it was difficult to upgrade. Probably won’t fly China Air again due to this. The attendants tho were much better than the airlines in the states and there attentiveness and care for your comfort far exceeds other airlines in the states.

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Delayed. Not a full flight and whole rows left open with the paid seating. Food was ok. My beef meal only had one cube of beef the rest carrot cubes. Entertainment on personal device but didn’t know about it until the flight was almost done.

We are glad to have used China Airlines for our trip. Continue the good service! Thank you!

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

I love my Delta crew, they were so welcoming and helpful.

The flight got delayed. They forgot to bring the drinks when I asked for it. The toilet is messy.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

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

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

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

Crew was great! Good meals. Had room to stretch out

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

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.
