Pros: "Food was amazing"
Cons: "The WIFI"

Cons: "Moré communication about the long delay."

Cons: "I did not take the flight since it was booked with wrong date and u refused to let me changed in24 hours although u did stated before booking that it can be changed without penalty"

Pros: "Comfortable seats, good entertainment options"

Pros: "I didn’t like the seat belt it looks like a car seat belt not comfortable. The food and the service was excellent"
Cons: "The WiFi"

Pros: "checking in, the agent pointed out that I had a middle seat. I thought I had reserved an isle. She fixed it."
Cons: "boarding using bus!"

Pros: "Nice plane. Seats fairly comfortable. Pleasant crew."
Cons: "No boarding organization (board rear seats first), mass chaos. Seafood spaghetti should be eliminated as menu item."

Pros: "They were very hospitable, and although it was a short flight, they fed us a warm snack. Very kind!"
Cons: "N/a"

Pros: "Ok plane, food was fine too"
Cons: "No gate at home airport when there's heavy rain? Even budget airlines pay for a gate, why not a star alliance member?"

Pros: "Very short flight"
Cons: "N/A"

Pros: "Everything"

Pros: "The in-flight service is better than others."
Cons: "The check-in process at Heathrow is a chaos. I’m not sure who’s responsible, between the Airlines or the Airport. It sholuld arrange separate rows between those already check-in online and the others. I also saw the officials let some (1-5) group of (3-8) people each bypass the long queue, without reasons. The seat and leg space are so narrow that the direct 10+hour- flight is not so comfortable."

Cons: "Seat don’t recline enough. Sure neck. Entertainment was quite limited. Needs more movie options."

Pros: "Nothing"
Cons: "No gate at landing, waiting for buses, long Immigration lines and then bags delayed. Time trying to get out of BKK was longer than the flight."

Pros: "They had good movie choices"
Cons: "The stewardesses, for the most part were rude, almost because they were lazy. I had one get pissed because I asked for oolong tea when she was offering coffee or hot tea. Well the cabin was so hot during the whole flight, I didn't want anything hot. She made it seem like she had to go out her way to get it for me. It was on her cart!!! They rarely walked around the cabin to make sure they couldn't get something for you or even take your trash. I held an empty cup during almost an entire movie. When I finally got up to toss it, I gave it to a stewardess who was standing right there by the closes curtain who acted like that it was beneath him to do so. They would rush up and down the isle and pretty much shove your meal on you. Ugh they were just rude. None of want to be there either, especially when it's so hot in the cabin and the seats were so narrow!!"

Cons: "The flight was an hour late therefore I was worried I’d miss my next flight. The “kosher” meal I was given was just an apple! Hardly a meal... and the flight attendants were quite annoyed as if they were bothered. I don’t think I will fly with Thai Airways again."

Pros: "All"
Cons: "Nothing"

Cons: "Our connection flight from Germany was changed and we were not informed meaning we land in Germany after the flight has departed. We're forced to buy a last minute flight with a different airline to ensure we do not miss our honeymoon plans"

Cons: "Being charged 5700baht on arrival check in for luggage. No mention of this as I booked through kayak!!!"

Pros: "seats are comfortable, service is mediocre"
Cons: "Boarding in Brussels is always a hassle. The plane is never ready for boarding and one has to wait long time to access the plane. They start boarding but do not open the doors of the plane so everybody has to wait long in the tunnel to access the plane. It would be better not to start boarding."

Pros: "The seats were fabulous. Roomy and my girlfriend and I were indeed placed in the armrest adjoined style. Flight was quite smooth. For the difference in price I can not fathom why anyone would fly coach on THAI."

Pros: "The crew are very friendly and helpful. There was a variety of entertainment options, with recent films, tv shows and music options to keep you busy. I also thought the food options were good, too. You didn't go too long without being asked about a new beverage or meal, pretty satisfying."
Cons: "The comfort could have been better. I find myself a little fidgety on flights anyway but I also had a sore back and couldn't seem to find a way to get completely comfortable, but I have had worse!"

Pros: "None"
Cons: "Lack of legroom"

Pros: "We took off at 11.30 on time but only arrived at 3.45 pm. No idea why it took so long on the positive side: I saw my movie till the end and it was an excellent one"
Cons: "Special screenings in singapore of all luggage: took more than 1 hour to get out"

Pros: "Comfort seat"

Pros: "We were flying business class and air china would not let us in their lounge until 3 hours before our flight but Thai Air let us use their lounge...we had 9 hours before the next flight. We will go out of our way to.fly this air line again"
Cons: "Not one thing was out of place...great flight."

Pros: "Boarding and in flight services"
Cons: "Nothing in particular"

Pros: "Attentive service, great food, smooth flight"
Cons: "Security queue when transferring at Bangkok Airport: Need more scanners and a fast track lane would be nice. Decor on the plane a bit tired with some paint chipping"

Pros: "The seats, entertainment and food."

Cons: "Flight from koh samui to bkk cancelled and has to spend 2 hours on phone to arrange another flight. Catamaran gave me the wrong phone number for calling thai airways. Thai airways/vayama had originally booked me on another flight without confirming it would have been ok. Terrible in flight service especially on way back."

Pros: "Vegetarian food was ok. Crew was very polite and helping."
Cons: "Economy class Seat was hard, did not move back much, had very less leg room, thus uncomfortable, couldn't sleep on the flight"

Pros: "Nothing - I had to cancel from China - took time. I then booked myself"

Pros: "Reasonably peaceful"

Pros: "Excellent service throughout"
Cons: "Nothing"

Pros: "The service was very good. Friendly cabin crew & smooth take off & landing."

Cons: "That Kayak did not inform me when bookinhg that the seats they were selling me had to be at the very back of the plane Last time I will ever use Kayak"

Pros: "The included extras and polite staff."
Cons: "When the passenger in the seat in front of me reclined her seat it was almost impossible to keep watching the movie which while sar, shows as mainly a black screen and even changing the angle didn't assist"

Pros: "Nice Big plane"
Cons: "There was delay leaving kathamandu for no reason. I also asked coffee from the senior purser (dressed suggested that she was) and she took my mug and never came back."

Pros: "Good seats in Business class on A380. Much better than BA, but not as good as Etihad. Cabin was too warm. Overhead lights flickering because of problem with bulb (yet on a fairly new aircraft)."
Cons: "Service was no different from economy class - perfunctory, reactive. No offers of any refreshments between the set meal times (not even water)."

Pros: "The Flight attendants were nice and helpful"
Cons: "Small confined seating area resulting in my hot tea being dumped into my lap as a result of the person in front of me reclining the chair"

Cons: "We had two drunks behind us constantly kicking our seats. There was three free seats in front of us, we asked to move there but we were told that those seats were for crew in case of turbulence. It's the first time I hear this. Half way through they allowed us to move for those seats."

Pros: "747, beautiful people and views"

Pros: "Everything was great(:"
Cons: "No massage on board, LOL"

Pros: "Cabin crew"
Cons: "Food"
