First time traveling with EVA.. great experience in economy class... Personnel very friendly..

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.

I was sleep when they brought the food. They had put a note on my seat. There was no food when I asked for food later. There was just one main meal served in this 14 hours flight. They offered me sandwich with ham which I don’t eat since I am pescatarian. Long story short I had to wait to get to TPE to get something to eat. I am extremely disappointed from the service. I have been flying EVA since I was 1 year old. Perhaps no more EVA for me. Seems EVA glorious day is long gone

Good. Please add a non- applicable category to your questions.

The app was awful. No accurate info. Paying for internet is a negative (Delta is free). The crew was very nice for the most part although you are not guaranteed to get good service. Some crew would ignore requests for things as simple as a cup of water if you were sleeping when the first serving was made. Food was great. Male crew member was exceptionally kind and responsive.

EVA air was nice. It was the first time I’ve flown with them. The poor entertainment choices for 2 long flights will make me think about choosing them next time. I didn’t know if would effect me so much but I couldn’t sleep and it added to the stress. The food was terrible for me but I couldn’t find how to inform them about my diet when I bought my ticket.

It was a good flight. I would highly recommend it to family and friends.

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)

On time service. Seat comfort and the crew service very good .

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

long flights are difficult but the crew and amenities made it a very good experience

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

China Airlines crews are very excellent doing their job. Very friendly and hardworking. I will always choose China Airlines over and over. Thank you all for making my flight comfortable. God bless to all the staff. :)

Staff was so nice and very helpful with directions aswell!

Most relaxing long distance flight I have been on. And I have flown on many.

It was our first time flying with China Airlines and had a very nice experience. The airline staff & crews both on the ground and air were very nice. Food on the plane was very good. Will recommend it to family and friends.

Not great, will likely try to fly another or maybe I should have upgraded my ticket? Needed Air…

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!

My ticket did not indication which group I was in for boarding; the gate attended help me

Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer

staff are super nice and effiecient! It was a very comfortable and relaxing flight

Boarding could have been a little bit better but other than that it was a pretty good experience. I think because of the stowaway to Paris France recently they are being extra diligent about boarding passes at the gate. But they boarded the back of the plane first, and that's something I really think needs to start in the USA.

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Food could have been better. Too many passengers getting up and down all the time.

Everything was great keep up the good work 😁, can't ask for more.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

The food options and quality could use some more excitement and variety.

Flight was delayed at the last minute for six hours. Instead of delaying it to a normal hour, they moved it to 10 pm to essentially make it a redeye. There was no compensation or benefit offered for this inconvenience. Once on the plane, Inpaid for WiFi twice with both times it not working because of a “weak WiFi signal”, according to the flight attendants. They also chose the farther possible gates in both airports from the entrance/exit, even though they were one of the few active flights left so late in the evening. Overall it was pretty horrible.

I had high expectations but met with a below average experience. I hope the Airline will take a notice and improve.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

Worst experience I have ever had with any airline in over 25 years.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

Everything was fine and I have no complaints or things to note.

The flight was delayed for 30 mins. The overall experience was good.

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.
