Crew is very attentive. Another new airbus 350-900 plane. Very modern.

Passengers were confused and freaking out coz the flight information wasn’t showing on the board that was running with all the departing flights. B9 gate was still showing Cathay Pacific bound for HK 15:50 was on until 22:07. STARLUX staff cameater but didn’t let the passengers go in to pre departure area until 22:45 for the 23:30 boarding time

The aircraft is fairly new. The screen is big and it's great to enjoy movies on a long haul flight. However, the food quality , and drink and snack selections, have room for improvement.

Preboarding food selection is an excellent idea. On the other end I did know the choice. People in my area know the choice. It ends with I got my meal till most of them are half way to finish their meal.

Overall it’s good . However the food quality can be improved .

My luggage was forced open and broke the zipper. I received it in a huge STARLUX plastic bag. Unfortunately, I have a round trip ticket but might be my first and last with this airline

I went to the gate that showed on the flight board but they changed gates at the last minute and I missed my flight. I had to buy new ticket from EVA air to Manila and take 3 hour bus ride back to my home. Will never fly Starlux again!

Starlux was great service and awesome food and drinks👍🏼 will take starlux again for my next vacation👍🏼

Loved the boarding process. All airlines should board from the back to the front. Very efficient. Food was excellent, crew were great, seats were spacious and comfortable and the entertainment screen was the best I have seen.

Flight cancelled due to inclement weather yet rival airline EVA Air with the same route departed 2 hours later and landed safely while our flight was cancelled and rescheduled for 36 hours later.

Certain flight crew member were rude and short with me when I asked questions.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

The crew very accommodating and food too is good. Keep up the good work

The crews are very efficient. Other airlines should learn from them when it comes to boarding and departing from the airplane. They also display efficiency in serving meals. They don't keep the aisles blocked for hours like some other airlines. The food is poor. Generally the food was unrecognizable and poorly prepared. The only thing that made it better than US flag carriers is that there was a fresh fruit bowl with each meal.

Staff show very stress with delayed flight more than passenger.

Very good service and food. Crew was professional and considerate. Cabin and restrooms were kept clean

Flight Attendants could have been nicer and food portions could be bigger.

Great experience, comfort and food is delicious. Always great service and one time

The food from Los Angeles to Taipei made me throw up. The flight is also not comfort. But the staffs are very friendly and nice.

I have never heard of EVA air before but I am so happy my wife and I were able to flight on their planes twice. Everything on these flights just felt better than their competitors. As someone with longer legs any bit of extra leg spaces is appreciated. The different options for food and drinks were also a plus. They were extra careful to make sure my wife's eating restrictions were taken care for. They had a before take off and landing announcements on the built in tablets for each seat and it gave out information that was very helpful. Such as what and how to declare your items in the specific country you landed in, any odd items that may be illegal to bring it (and even the reasoning why) and any other information you might need to make your post flight experience better. Oh and the seats were more comfortable, had more ability to lean and the headrest was much better for flight sleeping. The only downside was there were "forced" ads on the tablet at take off for maybe 5-10 minutes but honestly, this flight was the cheapest option and had all the benefits listed above that is such an easy trade off. Im keeping an eye out for EVA air going forward.

Flight attendants. Food, entertainment and most of all, be on time.

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.

Hour late but understandable under the conditions. Taoyuan airport could have clearer signs language wise and more staff to help direct people.

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.

Overall was a lovely experience. The crew were kind and courteous throughout the entire flight.

Better organization of boarding procedures. Terrible leadership guiding people to gates.

I did not like how the plane landed. It was not smooth.

Been flying with China Airline over years many times. Good experience with them, no issues.

The customer service was excellent. They noticed that our connecting flight was scheduled too closely for us to complete customs, so they changed the flight. Our initial flight was delayed, and they were able to get us on another flight, all without charging us any additional fees. I would fly them again anytime!

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

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

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

Coming back to America was a peaceful flight everyone and everything was perfect

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

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

Flight was too cold. I wore a regular cotton tee and it wasn’t enough. It was a night time flight so I would have thought a blanket would be provided to passengers. A 4 hour flight and no options for a meal? I flew Asiana the next day from Seoul to Manilla. Same duration, 4 hours. They give everyone a pillow and blanket and serve a meal. Why is United so cheap and holding back meals and amenities? Also, they promote too much gay stuff and DEI in their advertisements. Please be mindful of other beliefs and don’t shove your gay ideology down my throat.

The flight crew and attendants are very professional and polite.

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

Very good flight and very kind crew Only thing is I wish there would be a vegetarian option for the meals

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

For a domestic flight, seats are ok, but fir us as tall dutchies, the legroom is too small. However, for a short and affordable flight, is not a big problem. Staff is still very nice and a complementary water very welcome.

2 hours delay, time changes started already 2 days before the flight

Average, not more then that. Cannot compete with Singapore Airlines

I bought the front row seat and made and early online check in but they changed my seat to the back row without prior notice. The inflight meal was too poor, only a piece of small finger food. The boarding is a disaster, everyone is stuffed in a bus in chaos. Doesnt worth the money at all.

Poor. Flight was delay without prior notice. Poor boarding. Poor meal service. Plane was dirty and smelly. Does not worth the money.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.
