Staff show very stress with delayed flight more than passenger.

Very good service and food. Crew was professional and helpful. Cabin and restrooms were kept clean

Flight Attendants could have been nicer and food portions could be bigger.

First time traveling with EVA.. great experience in economy class... Personnel very friendly..

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

The flight attendants should be nicer, on my first flight I told them I’d prefer a veggie meal sometimes and then she began to lecture me about it, it was a late flight and I wanted an easy digestion meal so that I can sleep quickly. The meals were abit odd, breakfast on my last flight had eggs, oatmeal and fish, did not taste good at all, strange combination. The economy seats are very tight and crowded, not comfortable at all. Overall for the price I paid I thought I was going to get more.

seats are pitched well. you don't feel too tight.

For the price, it was better than other airlines; quality of food and service was very good.

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

We travelled in economy, were very satisfied with the comfort and keg space of the seats. Food was great compared to other airlines, the crew were very helpful and friendly. Since i was travelling with kids, i needed assistance multiple of times. Will be definitely taking long flights with Emirates from now on.

Very pleasant.The crews are very nice.Food were excellent.

Very pleasant.The crews are very helpful.Food are very good.

They should resume the fast track for business / first class passengers

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

The service on board was excellent, the flight wasn’t overbooked and we departed and arrived on time.

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

Emeritus is ***** Fly dubai is 0 we need better service for Fly Dubai

Flight was pathetic, felt like a old plane was modified and brought in service. Didnt like the aircraft at all. Crew and services were good.but aircraft totally dissappointment.

Business class on this plane was adequate, service, amenities, swag, and crew was amazing!

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Terrible. It’s like they are stuck in the dark ages. I brought a standard carry on suitcase and a back pack - I was told I could only carry on 7kg per bag - in business class, I was forced to remove articles from the suitcase and put them into my backpack! That’s the most ridiculous thing I’ve ever encountered in all my years of flying. The two bags weighed the same amount but one could not be more than 7kg. Holy cow.

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

I give EVA 5 stars in every category. I enjoy this airline and it's great team of employees. I always highly recommend EVA to friends and family and everyone.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

Entertainment is limited with a relatively old catalogue. Wi-Fi never works and the cabin and lavatory had evidence of a lot of scuff marks and temporary repairs. Nothing unsafe, but a bit tatty in places.

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

I felt that when I was rerouted it should have been to business class.

I’ve flown with Qatar multiple times and the service has always been great. Very professional, organized, the food is delicious and plentiful, tons of entertainment.

The American/Hollywood movies in the entertainment system lack english subtitles, they tend to have only arabic subtitles. Coupled with the low quality airplane earphones and cabin noise, it sometimes is difficult to follow the movie dialogues.

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

I purchased Qatar airways after seeing ads about its service. To my surprise Qatar is marketing gimmick and horrible airlines which I don’t recommend to anyone Flight was dirty including flight from Miami to Doha And Doha airport restrooms are dirty On top of this they use this pathetic cheap indigo From Doha to Hyderabad which I will never fly Also they lost one of my baggage in Indigo and still waiting to receive it. I will never travel Qatar and will never recommend

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Food no variations only beef of chicken no veggie meals

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia
