Excellent airline. The plane was clean and the staff were very attentive

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

Always liked Thai Airways but in the past they have been very expensive, not being a millionaire just yet, I will use cheaper airlines. Bangkok to London £370 11 hours 45 mins. Old plane but ok. Lovely ladies on board, very polite. Food was ok. Will always use them if the price is right.

The transfer from Domestic and International was a bit confusing but I am easily confused. I did not eat any food, but the food on the other leg was decent. It was nice they turned the lights off on the night flight. The plane was in good shape, but was a little cramped in economy and I am small. They gave me a customs form to fill out and nobody looked at it as I went through customs. Not a bad flight.

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.

Excellent service. departed on time, and arrived ahead of schedule. The whole restrictions around no food/drink is a bit weird even with Covid. Also, no mobiles and iPad use during takeoff and landing is very 2006!

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

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

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!

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.

No way to talk to support. Is all online self help or chat bot. Now way to speak to a person and the automated options are useless.

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.

Direct flight to BALI was good and convenient. Improvement suggestions - provide complimentary water

50 minutes delay on boarding,but overall delay time almost 2 hours on arrival.

I specifically searched for flight with checkin bags. Airfare assist website still sold tickets without check in bags and I had to pay 3 times more for my bad. Worst experience ever with untrained staff and haphazard boarding

As a frequent flyer, I was impressed with the smooth take off.

No frills means no frills... I just got on the plane and flew. That's all. Nothing more and nothing less. Or I did buy some water, they took cash only! LOL

First the flight delayed 1 hour ND then when we suppose to landing the pilot decided not to land at the chiang Mai Airport but the chiang rai airport

Everything were ok except that if we wanted to drink even a glass of water in the plane we had to pay !!

Great from start to finish. Staff very friendly. Flight smooth and comfortable.

Delay of 3 hrs and they offered only Macdonalds pineapple pays. Not any good

The return flight was delayed for more than 4 hours. Luckily we were in the airport way in advance and managed to reach out to the Nok Air sales office to squeeze us into the earlier flight.

Lead flight attendant was rude and not helpful. Very unprofessional.

Purchased additional baggage and the flight was canceled due to covid. When they rebooked us they didn’t carry over the extra baggage. They wanted to charge 3x the original ticket price for “added” weight… 6000 bhat for an additional 15kilo (which would of been easily covered by what we originally booked) took nearly 2 hours to work out and they only let us check in minutes before our flight boarded. Very unhappy.

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.
