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 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.

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.

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

Ontime, no frills, the cabin is clean, the ticket price is lower than the full-service airlines.

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

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

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

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.

well it was a short flight so there was no food but couldnt answer that question with a N/A There was no entertainment so N/A but the flight was great and staff was number #1

Never on time when I fly and Thai Vietjet App is too complicated. I had booked und paid for seat number 15A but when checked in, I got another seat number and row. I paid extra 50 bath for what??? They couldn’t change and I got no refund. No time to discuss with the ground crew to change it. I would never pay for seat anymore.

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

We were packed in like sardines. They did not even serve water on the flight!

Everything was good just the part on the need to transfer via bus to plane

Around Asia, Vietjet is always my favorite airline. Great service and beautiful stewardesses :)

I get tired of Viet Jet's regular delays. I tell myself every time that I need tp switch to Air Asia, which I have, but AA doesn't always have flights when I need them. Oh well...

Worst experience, hands down. With a movable departure time it's impossible to know at what time to go to the airport. On the day of my return flight I received a kayak email informing me that my flight was bent rescheduled for an hour earlier. I literally had to run to the airport to learn it wasn't true. Never again
