There was no screens on the flight, and no wifi with which we could connect to the internet and stream any content. This was a smaller plan so the business class seats were a bit tight. No hot towels or welcome drinks like when you fly on the bigger TG on the same route. The food was excellent, much better than the previous Thai airways business class meals. It was also nice that they offered eye masks for easy sleeping.

Excellent service in business class. Well worth the slightly higher fare as it includes lounge access, additional luggage weight and a full hot meal on board.

We still get drinks and a snack. Love the gift bags too.

Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

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😉

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

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.

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!
