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.

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.

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.

3 hours delay ,we changed plane after boarding and waiting inside

Uncoordinated boarding, seat comfort is terrible, even toilet is so small that overweight people wouldn't fit in. Baggage scam with additional fees. Stay away from this airline.

Forthright communication to the customers regarding services offered and any fees involved.

Scoot is a no frills budget airline. Do not expect a legacy airline experience.

Food & lower the prices. Look at Air Asia food look better & affordable

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

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 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

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.

It would have been nice if I could have actually travelled to Perth. I injured my back and was unable to fly. Scoot refused to change my ticket saying it was not flexible. However I purchased the ticket through MyTrip and it was flexible. MyTrip wanted to charge me an extra $271 to change to a ticket that was only listed as $217. Never again will I fly Scoot or book through MyTrip
