Aircraft was late getting to the gate - probably due to weather. We left the gate one hour late and had to wait another hour since we lost our slot in the takeoff queue. Our box was very wet and was falling apart when we got to Clark. It appears that luggage was exposed to weather in TPE while waiting to be loaded. Crew, however, handled the delay well and was able to provide planned service.

Sub sandwhich for a snack through mid flight and giving a bottle water was a good idea

seats are pitched well. you don't feel too tight.

For the price, it was better than other airlines; quality of food and service was very good.

I appreciate the email reminders for online check-in which made my entry to the lines less stressful. The flight was on schedule and on time. The baording staff were proactively helpful and approachable. The airplane inflight food, entertainment and comfies as well as provisions are excellent even in the economy seating. The airline transfer was smooth and easy! Luggage safe and intact! Thank you EVA airline for making my trip a reliable safe and comfortable experience.

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

The food is quite mediocre. I had spaghetti and the tomato based sauce was quite salty and there were no other flavors, no spices used in the sauce.

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.
