The flight was ok. The person who brings tea and coffee totally forgot about us or just walked past at both meals. And special attention is given if you are Taiwanese

The flight was ok. The person who brings tea and coffee totally forgot about us or just walked past at both meals. And special attention is given if you are Taiwanese

The quality of the food is pretty good. Thank you, EVA Air.

Fast and efficient boarding. Flight was on time. Service was very good for our long flight. First time flying with this airline and I would highly recommend.

Eva Air's Business Class is pretty decent. With the given price, I think that the food can be better.

Poor food on board, but seats are too small and uncomfortable

Staff’s were polite & helpful. Love to fly with Eva Air!❤️

Boarding is fast and easy for economy class, food was ok baggage policies are good

The flight went well. Everything good. Boarding. Meal service. Snack (crackers) & Drinks. Entertainment was good as I watch 4 movies. The need to have milk for hot black tea though as coffee creamer just never makes tea taste nice.

Everything was fantastic! It was a short flight but the crew really went above and beyond to make it a great flight. I felt cared for with EVA.

Liked the check in process, the service, and bathrooms being cleaned and stocked regularly. Food could have been better. I suggest serving some snacks or sandwich mid way some time after dinner and before breakfast.

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

The transfer from Domestic and International was a bit confusing but I am easily confused. I did not eat any food, but the food on the other leg was decent. It was nice they turned the lights off on the night flight. The plane was in good shape, but was a little cramped in economy and I am small. They gave me a customs form to fill out and nobody looked at it as I went through customs. Not a bad flight.

We are satisfied with the cabin crew serviceand the quality of meals served.

Lunch Food was tasteful and had variety. Seat was comfortable. However, when I was reserving my seats during booking, the seat configuration showed was 3-3-3, but when I boarded it was a 2-4-2 configuration? Also during booking, I had also bought travel insurance together with my TG booking. However there was no confirmation of my purchase from Allianz and TG. After several emails with TG contact, sales, reservation and Allianz was i able to confirm my insurance purchase. When the policy was issued, the birth dates of me and my wife were wrongly stated and I had to go through another round of emails with Allianz to get it corrected. Otherwise any claims would be void! It was indeed not a very good booking experience!

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

Thai Airways is one of the best airlines in the business. Looking forward to fly again with them.

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.

Efficient like all the other flights with them. An outstanding budget airline!

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."
Pros: "No..no redeeming features.."
Cons: "Coffee was the worst I've ever had. The 2+1 powdered mil and coffee stick. Truly awful. But i suppose there aren't many people on the flight who would order coffee..I would even pay extra for a coffee if they had a quality option. Food is comparable to a school canteen. I would probably pay 20rmb for this in Shanghai. Frozen butter for the half-frozen bread. They really couldn't do worse..."

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Overall it was a very good experience. Boarding was efficient and well organized. The cabin crew were excellent. The meals were tasty and quite filling. The warm bread rolls were a nice touch. Seats were comfortable even if they were a little narrow. Entertainment selection was excellent.

The staff at the check in lied. I requested aisle seats he said he gave me aisle seats. In actuality he only gave me aisle seat for 2 hour Karachi to Doha flight. From Doha to Dallas flight he gave me middle seat .

Too many boarding protocols. Never experienced with other international flights.

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Terrible. The website insisted that I wasn't logging in correctly to confirm my flight. It also wouldn't let me register as a member. I was unable to get a boarding pass until 4 hours before the flight so I couldn't get through security and had to wait. It was unlike anything I've experienced in decades.

Very bad. We booked 8 months in advance for 2 people but couldn’t get seats together. Food was so bad I couldn’t even eat.

Fine. Don’t think I would fly with them again

Lovely aircraft and I flight entertainment. Good leg room. Full flight crew struggled a bit

Online was good boarding also but a child was crying all the way with no intervention from crew member.

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

1st time with. Etihad Airways and it was amazing from check in to crew. Great flight.

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

Very unfriendly team. It was very difficult to get a cup of coffee. Legroom was extremely small. Old, dilapidated plane.

Crew did not cooperate… I just asked water twice for one crew member and she didn’t get anything.. and when I asked other crew member he gave me water and he was not respectful.. I kept Hindu non veg meal chicken .. when I get my turn chicken was not provided and then they gave me veg paneer and green peas curry which I don’t like..

Very very bad service very tight seats never ever flying with Etihad again

Everything was great. Cabin Crew was awesome and very helpful. Thank you so much.
