On a 45 mins flight to Koh Samui from Bangkok we were served delicious shrimp pad thai and hot tea. The flight crew did an awesome job serving a full flight.

Seats are tight and leg room so small. We had deep impressions under kneecap from the seat in front. A sign that Bangkok Airways is fully aware how small it is built is the cutout in the table. Very uncomfortable for people in size 1.80 m or more.

This is my 2nd flight with this airline. Service is very good. I was surprised they served a meal on such a short flight. The airplane landed so smooth that most people were unaware the plane had just landed. About half of the people on board applauded.

The staff were helpful and very pleasant. The food is tasty and there’s plenty of water provided. Flights are well air conditioned.

The food was inedible- The rice was hard as a rock The chicken was hard and could not chew Horrible meal. Don’t even serve it. It was an insult to think that you would have even served it.

I fly Bangkok Air regularly. Could say I am loyal to their airlines and program. The only two comments of critique I could offer is (1) using the credits from accumulated miles is not as streamlines as some of the other airlines programs I am or have been a member of... and have lost opportunity to use them before expiration. (2) Sometimes, the plane is boarded / un-boarded with a service bus that has to navigate the airport and adds unwelcomed overhead time (especially during de-boarding). If have checked luggage this is transparent; if only have carry-on will slow your departure from Suvarnabhumi by ~20 minutes or more. Otherwise, a fine airline.

Should be better if they provide more decent snacks. Also my flight took off was delayed by 15 minutes. I'd like them to improve to more punctual timing.

Bangkok Air has been hit with the challenge of flying during COVID like everyone else. Still, they are early to get started again and offer normal services when possible. It is nice to have a lounge for all passengers vs. going to gate and sitting to stare out at planes.

Pros: "Overall, the staff managed well the extra challenge of shutdowns and restrictions introduced by COVID. No complaints from me!"
Cons: "Honestly, Bangkok Air is one of my preferred regional carriers. "Normally" the food served is tasty, the plane is comfortable and the staff quite efficient. I have travelled a lot in my life and if there was a shortfall, would say so. Then again, I don't nitpick what professionals need to do to accomplish their jobs."
Cons: "Very good food and launch in gate but in check in they took my powerbank."
