Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

The flight attendants ignored us several times which was annoying. The sandwich thing wasn't very good but it's only an hour flight, it would have been better to have entertainment over bad food.

It was good overall. At 6 foot 1 it's hard to say anything seat on a flight is comfortable but it would be nice to have more legroom. The meals were good but would have liked to get wine much sooner.

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

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

It we as a pleasant flight. Good helpful and happy cabin crew. Food was okay, not to write home about. Drinks good. Entertainment okay.. Seat space good , comfort acceptable

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

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

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.

Food & service very good next I will pick up again

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

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

One hour before landing was the most scary part of my life. The plane just dropped from the air . No explanation or apologies from the captain. Women and children screaming everywhere. Would like to know what happened

My laptop in checked suitcase disappeared. The check in lady asked about it and found this very curious. She made me sign something when I insisted it remains in my checked suitcase. Robbery without violence.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

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.

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

Plane was clean, bathrooms were clean. Staff were very polite. Coming from Air India it was a welcome change.

Very tight seating. Crew seemed too dis interested and too slow to remove main meal trays.

Limit the number of usage of wine or please arrange our seats. The passenger was drunk on this flight and not on Thiruvananthapuram to Abudhabi.

Food quality and varites were very minimum. Surprised to have no desserts. Business class tickets should have lounge access and seats selection. They should be allowed to board while people with wheel chair, secial assistance and family with childrem.

On this flight...fine. The one from India to Abu Dahbi, awful.

1 hour flight. No complaints. Some drinks would have been nice.

Wish the flight attendants were more attentive in serving food

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

Liked leg room Disliked unable to book to sit with my family on same flight without paying extra

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

Food and beverage service have rooms for improvement .there were no entertainment facilities available

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

No drinks in business class after one glass of wine. Really poor interpretation of a vegan menu.

Business Class window seat on my Shanghai to Venice route was broken and could not be converted into a bed which has to switch to a narrow aisle seat instead

Suck! Sat in plane on the tarmac (hot) over 2 hours

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

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

Cheapest option from Gatwick £400 cheaper than Emirates and Qatar. Entertainment no where near as good as Emirates and Qatar, but saved £400 so all good.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.
