First international flight where the meals were not to my taste.

First international flight where the meals were not to my taste.

Overall, my experience with EVA Air was mixed. The highlight was that the airline clearly tried to provide a premium dining experience by offering the Michelin-starred Kanpai Classic beef yakiniku rice. However, in the limited space of an economy-class cabin, this meal felt overly oily and not very practical to eat. The sauce and grease made it easy to get one’s hands or tray table dirty, and after the meal many passengers may need to go to the lavatory simply to wash their hands. While the food itself may be high quality, the presentation and practicality did not seem well suited to an in-flight environment. Another disappointing part was the paid Wi-Fi service. I paid for the internet package, but the service did not work properly. What made the experience more frustrating was that passengers then had to spend additional time requesting a refund, and the refund process itself was slow and inconvenient. For an international airline, I think a malfunctioning paid service should be handled more efficiently. As for the seat, I feel EVA Air’s economy-class seats may be more comfortable for Asian passengers or people with smaller body frames, but they may not be as comfortable for taller or larger Western passengers on long-haul flights. The overall cabin environment also varied during the flight. Some passengers were not very mindful of noise, cleanliness, or shared cabin etiquette, which affected the comfort of the journey. I believe clearer reminders from the airline regarding cabin manners and hygiene could help improve the overall passenger experience. In short, EVA Air has some strong points, especially in trying to offer a premium Taiwanese-style service, but there are also areas that need improvement: more practical in-flight meals, a more reliable paid Wi-Fi system, faster refund handling, and better cabin management during long-haul flights.

Other than spotty internet, great servic, comfortable and smooth flight!

Crew was good. Sometimes food was eh. The spaghetti is gross for me. First time i got food, they didn’t provide utensils so i ate with my hands. I was hungry. They gave it to me 20 mins later when a crew member came by. I would fly with them again. Nobody is perfect

Eva air was fine - Trip.com via KAYAK sold my family access to a “VIP” lounge fo a layover in Taipei… i’m please look at my pictures. It was a scam, Trip.com knows it and they are perpetrating a fraud through your web site.

My flight was amazing smooth and the attendants were so friendly and nice

Crew are excellent. Food was good generally. Seats are small and there isn’t much leg room. Overhead bins are very small.

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.

Best flight in years. Pre-boarding because of my mobility issues. Good food and beverage from beginning to end. Excellent choice of films. Good service by stewardesses. Comfortable seats. I could lie down!

No drink service but there was no N/A as an option to choose. Seats were extremely tight. I am under 5.5 and I bumped my knees have no idea how taller people could manage.

Bad check in experience. Dirty ancient aircraft. Truly awful food and this in Business/ First class.

I truely appreciate all services. I was highly impressed and will not hesitate to recommend United Airlines to friends and family. The AVML was perfect.

Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

The lounge was not accessible because it was located before the passport control, and backtracking was impossible.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

Entertainment center did not work and no electric available at seat for 11 hour flight. Didn’t have access to overhead light or call button. Food was tasteless and had a high salt (27 %) of recommended daily salt intake

What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

Very friendly and attentive flight attendants, good food service. Seat was comfortable. However, the in flight electronics were poor. The screen froze repeatedly; the controller died; the headphones are a hit or miss; the wifi wasn't usable. Very scarce communication before the flight (no email reminder). Almost impossible to understand in-flight communications (audio was very poor).

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !
