Excellent airline. Seats were very comfortable with lots of legroom. In flight service was excellent as well

We were pleased with the flight experience. Nothing to complain or shout about. Unfortunately the rating scale in this survey will skew the results and give a false impression of what really happened. For example, we didn’t use the entertainment system yet we are forced to reply. A far more insightful scale would include “not applicable.”

We flew business class this time. The food in their economy class is much better in general. Also only coffee, tea and orange juice is free. Beer can be bought only. Same as economy, so their business class service is poor.

Nice flight, stress-free but why bother serving a meal on a 55 minute flight. From what I saw there was a lot of waste because travellers weren't interesting in eating on this short trip. Get rid of the meal and cut the price.

Generally good. I didn't have any food on the flight so I can't make a judgement. It smelled good.

Efficient, comfortable and clean-very good flight with friendly staff and crew

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.

Direct flight to BALI was good and convenient. Improvement suggestions - provide complimentary water

50 minutes delay on boarding,but overall delay time almost 2 hours on arrival.

I specifically searched for flight with checkin bags. Airfare assist website still sold tickets without check in bags and I had to pay 3 times more for my bad. Worst experience ever with untrained staff and haphazard boarding

As a frequent flyer, I was impressed with the smooth take off.

No frills means no frills... I just got on the plane and flew. That's all. Nothing more and nothing less. Or I did buy some water, they took cash only! LOL

First the flight delayed 1 hour ND then when we suppose to landing the pilot decided not to land at the chiang Mai Airport but the chiang rai airport
