Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Always enjoyed flying with Emirates, flown with others but they don't really measure up. The others are cheaper without a doubt, but not as good as Emirates

The stewardess took a picture as a gift , if you asked for it. Every thing was very good, Especially the food, big and tasty. The service was good, they served water several times, very frequent.

Child’s meal was great along with other nice touches for kids.

The journey was nice, all the crews were very good and services are excellent

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

It was delayed for 2 hrs. Flight attendants were not attentive.

Had to do shuttle bus both times during the transfer. It was waaay longer than acceptable. These 777s need a refurbishment really badly. Emirates and Dubai Airport used to be top notch. Now overcrowded and outdated.

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.

the rudest staff in the world!!! we had overweight baggage, which is our fault but it is a really stupid rule, and the woman said we could reorganise or pay now, we said we’d reorganise and she started shouting “do it now! hurry up!” even though the flight wasn’t even boarding yet. She told us that if our two cabin bags were below 14 together, then we wouldn’t have to pay 500k dong. We reorganised and our bags were below 14kg. She then said that it was all of our bags together that should be less than 14kg. We were obviously confused by this, because she had just said that it was our two cabin bags and we asked her why she told us to rearrange our bags then. She started shouting at us again saying that we needed to “pay now or throw away”. We said fine, we’ll just pay, and she suddenly started asking for 1.51 million dong. I asked her why it was suddenly over three times the price and she said that it was always that price. I asked to see the other piece of paper she had that had the other price and she slammed her one on top of it and started shouting “pay now or i’ll close the gate” (boarding was already finishing at this point). So, we had no choice but to pay three times the original price, even though we reorganised our cabin bags to be under the necessary weight like she had asked us to. I wouldn’t even be so upset about the money if the staff were at least a little bit nice. She was possibly the rudest, most ignorant woman I have ever met in my life. Besides that, the plane/flight was just a bit worse than ryanair standard. Small seats, delayed by an hour. Typical low budget. At least the ryanair staff don’t try to scam you. Avoid at all costs, it’s not worth the hassle of dealing with such horrible people.

The boarding process took very long, partly due to passengers on incoming flight took too long to deplane

The flight left on time and landed early. The attendants were polite and friendly. Thank you

Efficient and fast check in, courteous staff at counter and on board. On time departure and arrival. AIR ASIA is my favorite international thailand carrier for reasonable cost and excellent customer service!

Delayed us three times, changed gates twice, and then tried to charge for food on the plane.

Not good in terms of amenities. For over 6 hours they don’t even provide complementary drinks or snacks-forget about dinner or lunch.

Air Asia just dreadfull. Always poorest customer service and very unwelcoming staff which is clearly bread in from the Top down from the CEO

Everything was good. The red seats were a scam. Just like any other seat but red. Although they let you board earlier which was very nice.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Very good, it would be good if payment for drinks could be accepted by card too.
