Not much to say really. It was very basic flight with no entertainment. But it was inexpensive and fine for a short flight. No complaints

Not much to say really. It was very basic flight with no entertainment. But it was inexpensive and fine for a short flight. No complaints

Easy boarding and friendly crew. There is no food offered as it is a short flight and no entertainment either…but a good experience overall.

A very nice flight. It arrived on time, and the plane was very clean and the staff was very professional.

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

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

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

No WiFi or movies. And the seat We’re uncomfortable. Good thing it was a short flight

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

We had a 3 hrs delay and they offer McDonalds pineapple pay. They charged us for extra grs of luggage and the experience was not good

I don't like this airline. The website is not user friendly. I tried to check in multiple times and no joy. Then I googled why might this airline not let me check in and it said if you are checking baggage you can't check in. I really thought that I had purchased baggage. Because I have been traveling for 3 months and making sure that I pay for baggage on every flight. This flight they said that I had not purchased baggage but there is really no way to check on the passenger side.

I wasn't able to check in. The website could find my reservation but then an error occurred. I tried 4 times spread out through the day and got the error message every time.

Delayed and very little leg space, my knees were into the chair Infront, when I put one leg into aisle out was overrun by staff.

Excellent experience nothing could be improved with staff. Was hoping someday the airline will use tape recorded lfor languages that are not common to staff. Probably with AI it might be a good addition

Need more where chair assistant helper I request, but no one help me.

There were four delays over a period of 3 1/2 hours with very little advance warning. There was no explanation offered as to the reason for the delays. I hope I never have to fly a Thai Viet Jet Air again.

Left 1/2 hour late and had to deboard on a bus. I will choose another airline from now on.

They cancelled my flight and never notified me. I needed to pay another airline for a ticket so I could catch my next flight. Which was 3x the price!!!!

If you need to check luggage, make sure you buy the allowance upfront via their official website. Otherwise a bag will cost you more than the airfare.

The flight boarding was very early and the flight arrived ahead of schedule.
