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."

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

Scoot refused to change my flight even though I had booked a flexible ticket. MyTrip wanted to charge me an extra $271 for a ticket that was only listed as $217. I complained about this to scoot and they didn't give a shite. So never again will you be getting money from me Scoot. You can Scoot off.
