Delayed us three times, changed gates twice, and then tried to charge for food on the plane.

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.

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

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

Pros: "This is a budget airline and they get you to where you going at good price"
Cons: "They pack you in all together even though there are open seats available and leave you there as if you've done something wrong"

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),…
