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.

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.

Airline cancelled our flight purchased through kiwi.com 2 months before travel and to date has inly refunded half of our paid ticket price.

Crew was nice, boarding efficient. VERY cramped seating. I'm a 5 ' 10'' slim woman and my knees were up against the seat in front of me and my arms were against the arm rests. There are no services, not even water, and they only take local currency and I didn't yet have Thai baht ( flying from Indonesia and no rupiah left). I won't choose to fly with this line again.

Good, no mini-tv's, no food unless you pay, good overall experience.

ได้นั่งรถไปขึ้นเครื่อง แอบเสียใจอยู่ พอขึ้นไปถึง มีคนมานั่งในที่นั่งเราอีก ไม่รู้เจ้าหน้าที่บนเครื่องไปแนะนำผู้โดยสารท่านอื่นยังไง เขาเข้าใจผิดว่าที่นั่ง C คือข้างหน้าต่าง และเที่ยวบินนี้ ดีเลย์แล้วดีเลย์อีก จากทุ่มสองทุ่ม ดีเลย์ไปถึงห้าทุ่มกันเลยทีเดียว ถ้ามีไฟลท์ต่อกันนี่คงไม่รอดแน่นอน

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.

I really like air Asia. The flights are running very professionally and both of my flights this last time got in early. Planes were clean. The staff was very professional and helpful. I understand they were supposed to be a budget airline but they don’t act like they’re a budget airline.

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

Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

Very professional and well managed. On time, great staff and comfortable.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

not looking like a national flag carrier.. both the ground team and flight team are far from being kind and helpful. Not sure what's wrong.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

I m not good serves poor serves I m m fake company kayak ok plzz my help my ticket cancel my tripe ok

Terrible experience. Unexpected wait due to staff delay was not taken proper care. Food inflight could be better where as flight attendees on flight hospitality was 100%

Aircraft used fir this route was pretty old. Seats 💺 were hard & difficult to reclaim although it was flat bed

Because of the bubble agreement b/w India and Srilanka, I was not allowed to board the flight to Columbo. My experience about airport representatives was good. They were through in their job and saved my family from getting stuck in Columbo (as I would not be able to fly to Doha because of bubble agreement). So by their prompt attention, such a catastrophe was avoided. For this reason, even without flying with them, I would rate them 7/10.

The flight delay... but bus from the airport be on time

Bad experience, delay like no tomorrow. Original schedule departure time at 9:30pm, delayed until 12:05am only depart.

Great. Very satisfied with a direct flight from Penang back to HK international. Stewards in the cabin were very friendly and helpful. Would not hesitate to fly with Air Asia in the future.

Second time flying on AirAsia. They’re fine for a low cost carrier, so I don’t expect high level hospitality. They could have informed us that the flight would be delayed even if by a few minutes, instead of the passengers asking the gate agents why we’re not boarding 8 minutes before takeoff. And given some of the passengers on this particular flight were problematic, the crew did great handling such people.

Meh, it was AirAsia. It's not about a quality.

Great flight. Achieve my objecttive of travelling with less hassle .

They didn't have a single blanket for hire for a long haul overnight flight. This wasn't good enough even for a budget airline

Kayak shares with you the best price! and in my case it was Air Asia flight. Air Asia flight was on time, the boarding was seamless with FACES technology at KLIA2 and the pilot made a great smooth landing upon arrival. Excellent trip!

I left the city late and fortunately the flight was also delayed 50mins

Air Asia’s standard has dropped tremendously post pandemic. The whole organisation feels ‘soul-less’
