Majority of the movie entertainment loaded in the aircraft were quite old.

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.

It was a pleasure to fly with EVA airlines from Taipei to San Francisco.

The soft service on EVA was superb from the quick and attentive flight attendants, to the turn down service, and excellent food. This all made my 11 hour flight very comfortable and relaxing.

I love EVA airline, but the KAYAK website for not in emergency, urgency and personal issues. For instance, on January 5/2026 with already booked the flight, I have a 15 hours of delay between airport when booked before as my choice. But if I want to go back home (U.S) early, then I have to contact the KAYAK office at I was in other country without phone service and nothing that EVA can do for me. Even I offered to pay more to change from another flight to go to the U.S early, not wasting at15 hours of delay, but EVA could not help me until I call KAYAK at an Island of nation. No office of KAYAK from any nation and times of difference in the world. However, everything and everyone is the best. Therefore, please KAYAK making much more easy for both the airline and passenger in some issues at the middle of nowhere in some country when no need to call KAYAK for some emergency, urgency, sick, etc or personal reference. Please, please, please no need to call KAYAK office for any changes of flights from urgency or private.

My seat arrangement was good with Eva Air. The toilet sanitary was good ( hand wash, face moist spraying, fresh air spray, hair moisturizer). But the Asian movie selection was not great at all.

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

Flight attendants are polite and pro. Missing of on flight entertainment is a big miss for a ordinary airline.

I had knee surgery a few weeks prior. I was using cane walking very slow. Crew were extremely helpful

Eva airlines has very goin service, despite being low cost. Meals and fin, not amazing, restrooms always clean and staff polite and helpful

Its fantastic!!I like the food the serve in EVA air😊

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

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 flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

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.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

Staff was so nice and very helpful with directions aswell!

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

I would like to commend the staff from this flight. They all looked happy and I can tell they love what they are doing and constantly smiling while serving the passengers. Special mention to the guy FA in our section. I did not get his name but he is so far the best F.A I have ever encountered!

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

No frills airline with minimal leg room and no entertainment

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

Food was just okay, need to improve for other menu variations

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

I have difficulties to book wheelchair for my parents returned flight

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The seats were comfortable and we had leg room. Great entertainment.

The flight crew where really good. Better then the crew from BNE to SFO

Delayed, toilets did not flush, pilot parked to far away from Gate

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Safe made to destination. Late to start at GVA for icy reasons but we fought our next fly.
