Overall a very good flight,staff on plane were very nice.And the flight was on time.A pleasant experience.

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

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

It was on time! First time in a long time for Air Asia. Thank you!

I get so tired of the constant delays, but there are so few options. The plane is coming from Bangkok each time. Why are the flights so regularly delayed. I do appreciate the speed of the baggage delivery into the terminal.

CNX is a filthy, poorly kept airport. I have heard that Thailand plans to build another airport in San Kampaeng area, so perhaps they are just letting this one go. But it makes every airline look badly to offer their service in such a poorly organized "dump". Sorry to say this, but that's what it's like. At least the AirAsia flight which I took was on time! I appreciate that.

Air Asia will be my choice of airline when I fly to Asia every 6 to 8 weeks. Thank you for your good service.
