Pros: "the flight was online, and the checking in process was fast and efficient"
Pros: "The B-class seats are fine."
Cons: "Crew did not offer blankets or earbuds. Dry flight! No beer, wine, or spirits at any price. I was astonished."
Pros: "Friendly staff and crew. Flight went as well as possible over the mountains from BKK to CNX."
Cons: "Took bus from gate to a different gate. Had to walk up three sets of stairs to walk on to a jet bridge that was connected to the main airport. In flight snack would have been better not consumed. No illness, just didn't sit too well."
Pros: "Huge plane that wasn’t full so it was very comfortable. Boarding was quick especially since I’m a Star Alliance Gold member so was one of the first on the plane. Bags also came out first & delivery was very quick. Looking forward to flying Thai again several more times this month & wish I could experience their international service which I’m sure is stellar."

Pros: "Value Friendly staff Cleanliness of plane"
Pros: "Crew were polite and nice. Food was good"
Cons: "Entertainment system was very glitchy, the headphones sockets on my seat were broken and loose."
Pros: "For such a short 1 hour flight, they managed to feed an A330 plane load of people - pretty impressive feat considering that US carriers don’t even bother to give complimentary hot food on a cross country flight. The color scheme didn’t hurt either. The FA’s were very accommodating and so pleasant."
Pros: "Nothing! The plane left late and while waiting, the airco blastwd like a freezer. My feet and gands became numb and I got a terrible headache. Next, a chinese couple with a 1 year old toddler came to sit next to m: the child started wailing immediately and this lasted until 5 min before landing. It was like they had not a clue on how to handle a child and they had nothing to make it drink or suck or distract it. Worst flight in ages.."
Pros: "Very nice and friendly staff. We were fed a small meal on a very short flight."
Cons: "Ran an hour behind schedule. We boarded on time and then got delayed waiting for air traffic control. Landed about 40 mins later. Considering it an was an hour flight, a little annoying. We didn’t have another flight to catch or somewhere to be, but it could have been troublesome for others."
Pros: "Nice plan, nice crew, left on time"
Cons: "Please offer a vegetarian option for the snack"
Cons: "Air Canada cancelled the original flight and rescheduled it for one day later. This was an obvious problem since it affected other travel plans. Air Canada customer service was very poor. First agent was unhelpful, second agent better. Overall it was a pain to finally get another flight for the original day."
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: "Punctual and efficient flight"
Cons: "Food was poor and staff were not at all friendly"
Pros: "On time"
Cons: "Nothing"
Cons: "see above"
Pros: "Friendly staff and airport folk! Smooth and easy all around!"
Pros: "Everything ok But just Ok"
Cons: "Bossy staff seemed to much trouble stretching your legs made you feel like you were in the way!!!!"
Pros: "They maintained darkness inside the cabin, thus I could relax well."
Cons: "Food was not good, also they served dinner at 5 pm which was very early for me. I had late lunch at 1:30 and was not expecting dinner at 5 pm. I did not feel hungry and so refused the meal. Unfortunately they served only a cup cake later in the evening. It was a 6 hour flight, thus a small cup cake late in the evening did not suffice."
Pros: "Organized polite people"
Cons: "Home"
Pros: "The flight was only an hour but the staff was crazy fast to get everyone a snack that was amazing. Hot food which is unlike American flights. Very tasty and the service was just good."

Cons: "Slightly dated fittings"
Pros: "Excellent, clean, up to date plane."
