Amazing customer service. BUT!! It would be nice if the flight attendants SMILE a little more, I know they are doing their job, but it is importantly to smile back and be warm to passengers. Nobody is trying to hit on them, it’s just being polite. So, please Taiwanese flight attendants: SMILE MORE WHEN YOU INTERACT WITH PAYING CUSTOMERS

What could have been better, was we were delayed from takeoff for two hours. Initially we were informed that we were delayed for refueling. Then we taxied out on the tarmac, then just waited there for a long time, with no explanation of the delay. Were we just waiting on takeoff clearance or was there some other reason for the delay? The pilot, nor none of the crew informed us passengers. That was not good customer service. That needs to be improved, whenever a delay, inform the passengers for the reason.

More seat space More bathrooms Charging outlets Plane was old

This flight was long and I am so thankful I had a seat in the back of the plane. As I usually must get up and stretch every hour . The crew were probably the most friendly I have flown with. Thanks and I will book again with Eva air. Food was ok too.

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

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.

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

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.

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.

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.

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.

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