Airline reviews

The plane was half empty and I lucky to get three seats to myself allowing me to stretch my legs. Even without that the regular leg space in economy was quite comfortable compared to some other planes in recent memory. Food was fine I’m not vegetarian, but neither of the options offered was. So order vegetarian ahead when checkin in.

So order vegetarian ahead when checkin in.

Picked our seats when we purchased this flight (2 seats alone on the right) but were assigned two middle seats in the middle row at the gate. Very disappointing for a 10 hour+ flight, and what is the point of picking and paying for seats ahead of time when they just reassign us?

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.

The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

I can't believe they put my wife and I in the two middle seats! It is a very long flight and we had single flyers on either side of us blocking the way to the bathroom! There's no reason to not give one of us the isle seat so we could have managed bathroom needs and snacks with convenience. So I think very poorly of Korean air to put us both in the middle, I've never had that happen before and will probably avoid this airline in the future because of this. We tried to have them change it but they didn't so you pretty much lost a customer because of it.

One of the flight attendants stepped on my foot. I was on the aisle seat. A lady inside needed to get out. So Instood. Just then, a flight attentendant came wuicklybtheoughbthe aisle and stepprd on my sock covered toes. I let out a small sound. She stopped momentarily, but didn’t ask how I was just took off of the aisle. Never came back to see how I was. Fortunately, I was not really hurt other than a slight soreness in my toes. But I found that to be very negligent.

Korean Air is unlike any other major airline I have flown with. The grace and respect that the staff has from check in to de-boarding is unmatched. The flight attendants this time were especially wonderful to my five little children. They helped us rearrange to more suitable seating, brought our children’s meals, and patiently waited for them in the aisles when they had to use the bathroom. We felt so welcome and comfortable. I really appreciate the meal voucher when our flight was delayed. I am grateful to have had such an stress-free experience.

It's good overall. Flight was packed. Inflight entertainment choices were lacking.

Long haul from Chicago to Tokyo was great, traveled in the ROOM on ANA and experience was great all around. The flight from Tokyo to Bangkok was fine. Definitely a good way to go. Should have stopped in Tokyo for a bit.

Refer to the Osaka-Tokyo one, it explained how I felt about both flights

I am a United 1K flyer but certainly I would fly ANA again. Great inflight service!

"The Room" is the only way to fly. The service was excellent and the stewardesses we all gorgeous and friendly. The boarding process was delayed and the attendants at the airport were not the best.

Great. Very helpful staff and accommodating. The flight was also smooth

My son flew and had a great experience.. thank you for taking care of my baby

Choice of movies dated as with the screens. Major room for improvement on the software to sort and select choices.

I loved everything about my experience!!! The staff were absolutely incredible. I can not wait to fly again with them.

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

we were in premium economy, but we both got middle seats and had to sit separately. i could have avoided this by trying to obtain seats sooner, but i tried 3 times and gave up. ANA's technology is not friendly for newcomers. no, check that---I think it is nigh impossible. not sure we are coming back. ana can do better to provide a front end that's friendly to users in both US and Japan.

It was a great experience had been wanting to fly emirates to Dubai for long time. Thank you to all the staff.

everything was great , perhaps lower pricing and more miles incentive and prolong expiration of miles

Enjoyed it very much, excellent aircraft, excellent flight attendants. I will be happy to fly Emirates Air again.

Good service. I wish there was more legroom. The food could be improved with additional options.

The crew was very attentive and delivered great service unlike any other airline. It was our first time with Emirates. Our only critique is the food. Pasta pesto is not very common. Tomato sauce would’ve been more of a crowd pleaser. Beef curry sounds bad because curry can be very tough on the stomach. We were in row 26 and the pasta ran out, meaning no one wanted the beef which says something. The beef was just ok… The rest of the food was very good and generous. The plane speaker sound could be better. It was tough to understand announcements even with headphones. Although we did not need them this time due to the purpose of our trip, we were surprised that 2 checked bags were included. That’d be great for the future. It was unpleasant though that our personal items were weighed (we’ve never had another airline do this), especially when we didn’t have checked bags and almost had our carry-ons checked. Overall it was a good experience, but we wish the prices were friendlier for such a short distance (Miami > Colombia).

It was very exlent flight and thanks a lot kayak

Flight was cancelled without notification. Information on flight status was not available on Emirates's website.

Sadly I couldn't get the food I requested as it was out. Also, if you don't want to be woken up make sure the crew knows it. My wife was woken on every service.

I wish any of the US airlines operated like Emirates

Better information about the delay due to screening for US

Love Delta. I'll take connections to stay on Delta even if another airline has a direct flight.

Crew members were nice and professional. TV, you have to press very hard on the screen to get it to respond and WiFi didn’t work. Overall okay flight

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

Sat in the plane at the gate in SLC for 2+ hours before take off, getting me home nearly 3 hours later than planned.

Really hard to tell what was happening after my flight got delayed five times

I’m on this flight every other week. Same flight, same day of the week, same time of day… Multiple times there are issues getting flight plan registered and FAA approved r to take off. PAPERWORK This is exhausting and it sucks.

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Flight delayed due to ground hold. Republic airways did a great job.

The flight was smooth, the crew was great but the plane was quite old

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.
