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

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

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

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

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.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

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😉

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

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.

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

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.

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

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.

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

Poor customer service! They don’t have 24/7 customer service. I was stranded in the transit area of the airport for over 21 hours. I was denied to board a plane without any help that caused my entire return flight to be cancelled. I had to book an entire new return flights. It caused me lots of stress, waste of my time and money.

What started as a small delay at checkin ended up being a two and a half hour delay by the time the plane took off. The annoying part was that we weren’t told what the holdup was.

Offer a pillow in business class for night flight. More comfortable seats. Offer alcoholic beverages. Get flight attendants that care.

It was not possible to do an online checkin with Nepal Airlines. Apart from that, all the rest was very good : good food, friendly staff that ensure that Covid rules are respected (not always easy),…
