HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

The boarding efficiency was good. A couple of the flight attendants did not seem in the best of moods. Overall it was a good experience.

The flight attendants ignored us several times which was annoying. The sandwich thing wasn't very good but it's only an hour flight, it would have been better to have entertainment over bad food.

Extra seat belt across the chest 10 minutes before taking off and 15 minutes before landing seemed excessively safe.

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

Efficient like all the other flights with them. An outstanding budget airline!

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.

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.

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

Very few crew meant that we had to wait almost 2 hours just the get a drink!

Thai Air Asia no longer has customer support that you can call and talk to. All support is done by chat bot or self help websites. This can be a major issue if you have a problem and it bit us so we can’t recommend nor will we book with them again unless as a last resort.

Landing to Hanoi in time Seat not reclining -Cabin design very dull

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 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.

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

Delayed boarding, deboarding by bus - time to choose another airline.

Middle seat after specifically asked for isle many times. There was a lot of room left. Passenger next to me complaining that she couldn’t sleep because I bumped into her. I’m a 6.5 guy what the hell am I going to do there?

No food or entertainment on this one hour flight. Crew were very nice as always!
