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

My ticket was with EVA Airlines, but Asiana Airlines was the ground crew for EVA Airlines. Me and my family member finally received our boarding passes after waiting to check-in, which took over 30 minutes. I had never done a tax refund before, so I crossed immigration without going to customs to receive a stamp for my tax refund. When I went to the tax kiosk on the other side of the immigration gate, NICE Tax Refund asked me to talk to an airline staff member. I could not find any airline staff member, so I went to the Information Desk. The woman at the Information Desk told me and showed me a sign that read that I needed an airline staff member to accompany me to cross immigration again. The woman at the Information Desk phoned EVA Airlines and Asiana Airlines. I also phoned, but there was no answer. There was still 80 minutes before my flight would leave. I waited for 45 minutes. I spoke to Information, not one time, but two times and the woman assured me that this situation happens often and it is nothing to worry about as the airport is small and once the airline staff arrives, it would only take 10 minutes to go get the stamp and I would be able to make my flight. Then, 35 minutes before my flight was scheduled to leave an Asiana Airline employee, accompanied by the woman from the Information Desk came. Asiana asked me to confirm whether I wanted the customs declaration stamp. I answered yes. Then, she said she would like to state that I should take full responsibility if I could not make my flight. She asked whether I wanted her to proceed to contact a staff member to take me to get the stamp. This was very suspicious as there was still 35 minutes remaining until the flight took off. I directly said to her that the question was very strange, but as there was enough time remaining, I did not see a problem and wanted a staff member to accompany me to get the stamp. She went away and came back 5 minutes later and asked me whether I had the item I wanted to declare on me and how many people were traveling with me. I told her I had the item with me and I was here with a family member. She then went away again for another 5 minutes. When she came back she asked whether all members would not be traveling as well. I stated that I am not sure why me or my family member should not board the airplane. At this point, it became apparent that she was not helpful, so I tried to talk to other airline staff. I also talked to a woman wearing a reflective safety vest, who was organizing the gate bollards for boarding and she said she would take me after boarding. When I asked, how I would board the plane, she then said, you will not be able to. I then talked to a man, who spoke Mandarin and appeared to work for EVA Airlines. He told me it was my fault and not his and tried to re-direct me to another person. He was not busy at all. At this point, it became apparent that, Asiana Airlines and EVA Airlines, were more interested in delaying and preventing me from boarding the airplane. In the time the airline staff wasted arguing with me, they could have just brought me to receive the stamp. It seemed apparent that I was not going to receive the stamp or the tax refund, so I stepped into the boarding queue line. Again, the airline staff, the woman in the reflective safety vest asked me to confirm that I would not be getting on the airplane. I was already boarding! There was written signage of the procedure at your airport’s Information Desk. Then, I was passed to multiple airline staff that were not willing to assist accordingly. There was no one at the customs declaration counter and no one else from the airport to assist me. EVA and Asiana Airlines both avoided responsibility and delayed the procedure. They were rude and indirect about the situation with every attempt to prevent me from boarding. Deterring foreigners to depart from a foreign country over tax refund issues is unlawful.

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

Flight was canceled was only given only a 8 hour lead time. Had to fight to be put on another airline (United Airlines) that was leaving earlier then the one EVA and rescheduled.

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.

Awful had to ask for a supervisor to sit with my flight companion even t booked the tickets together weeks before

EVA airlines was excellent: on time or early, safe, courteous crew. Highly recommended.

EVA! What is going on with your food!?!? Pre pandemic I used to go to Taiwan at least twice a year and always flew EVA — the food was consistently tasty for airplane food. Post pandemic, it’s not great at all. Step it up!

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.

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