Flight was smooth no complaint. Except maybe better food choice for the long flight…

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

Everything was excellent service was good.Only one problem my trip san francisco to tapie was good but the Taipe to HongKong we change gate 3times a lot of walking n everyone has to rush around from gate to gate.By the time to board our flight i felt soo sick from running from one gate to another.That was the only problem i face

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

Pleasant crew. Very long flight, a bit uncomfortable at times being seated, but not too bad.

Eva air is a good airline. The seats on the way to Taipei could have certainly been more comfortable, but all in all it was a pretty good experience.

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

Overall the flight was what might be expected for a long haul flight to Asia in economy class. The cabin crew was attentive and the food was good. Boarding was fairly fast and easy. The one thing I found frustrating was the EVA app. It is terrible. Trying to do anything on it was almost impossible.

I hope their usb charging port works. None of their usb port is working. Boeing 777 LA to Taipei (vs)

seamless check in/ friendly staff, food is good, always love flying Eva Air

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!

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

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 😊 🙏 😀 😉 👍

Online check-in doesn't work. That's why I couldn't give it full Star.

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 .

Just money making business. This was my fourth journey with Qatar Airways, year by year the quality of service getting poor. Food is very cheap. They have some low quality alcohol beverages. They don’t have any brandy or cognac. No toilet around the gate lounge. We have to wait until getting to the flight for use toilet.very long standing for entering into the flight. We can see the old passenger suffering.

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

Overall good but staff in the place looked extremely tired after 8hrs in 14 hrs journey and then service was cut short and response time for calls increased in later part of flight. Food was ok not astonishing

They ran out of some of the popular food items. 😞

Was unable to check in via app or website with supplied booking code (something to do with flight being operated by a partner airline, although the code didn’t work on the partner’s website either) Specified a vegetarian meal during booking, but that somehow wasn’t captured in airline’s system By the time flight crew got to my row, now vegetarian food was available. Had nothing to eat on flight from Philadelphia to Doha! Flight attendant was completely unconcerned and actively apathetic to the situation

Overall mediocre experience. Check in was good. They're were discriminatory. They were not attentive, food choices were not vegetarian friendly. The food served was frozen.

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

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

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

Ripped off and broken seats in Business class. Seats stink and need to request the staff for additional bedsheets. Crew if very friendly though

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Crew member took too long time to take back leftover food plates from passenger seats. Food was nice.Easy excellent checking.Guy at checking counter was really kind and helpful.Made our checking very quickly. Leftover food should be taken back ASAP. Because in economy class passanger have narrow space . In the long journey like this, passanger have difficulties to sit with the plates.overall experience was good.

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

Check in was quick and gentleman was very nice and friendly, during flight crew members were polite and attentive, food wasn’t as it should’ve been. Entertainment section needed to be updated i.e add new movies

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

Pros: "Friendly crew and helpful staff"
Cons: "Missed connection from PEK to XIY due to delayed arrival and early departure. From XIY to PEK, booked and confirmed 11 departure, changed to 12:30 without notification or explaination. Rushed connections at PEK, pretty much ran from the minute left plan to another terminal, through custom, through all the health check points, security check. Just keep the fights on time and keep the original schedules, not arbitrarily change them."
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
Pros: "The food was good. It was nice that they supply wet hot towels before each meal. The seat was comfortable with the price I paid for. The rest room is nice and clean and quite spacious. The L’occitane toiletery bag was nice."
Cons: "It would be nice to supply mouthwash in the rest room. It would be nice to have a foot step at the bottom to open the trash container. The comforter is not washed and smells."
Cons: "Even for business class there is no TV screen on each seat. Just one small TV screen on the ceiling for a few rows to share. It would be much better with TV screen on each seat. I was sitting in the first row business class and the air hostess skipped me and didn’t give me a slipper. She gave me a used slipper at the end only without a packet. This is unprofessional to treat a business class passenger"
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The seats on business were comfy, the service excellent, the movie selection was fair to poor, the food was also fair to good largely because they served a heavy lunch rather than a light breakfast."
Cons: "The food and movie selection."
Pros: "Crew was great and was happy to get gluten free food i could eat"
Cons: "Not lose my bags :("
Pros: "Beautiful new plane, professional crew, totally decent food."
Cons: "Economy for 13 hours is always a bit rough, but no more so on Air China than any other airline. And the price was so much lower."
