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.

Captain smooth landing, Crew efficient and helpful. We saw Mt Fuji from the plane. Thanks.

On time and smooth flight from San Juan direct to Sint Maarten.

Just to be expected on a budget airline. Since all the flights were either late on the evening it would help to offer some food for purchase Since you tourists cannot buy decent food withoit local vaccination record in hong Kong this would really to help Using phone to submit electronic data is great but for the elderly this is a hassle

Flight cancelled without notidication, had to book an emergency replacement flight at the counter

Cons: "We should have been allowed to sit near our family (wives). There was empty row but they wanted to charge us to move up. Ridiculous!!"
Pros: "Absolutely nothing"
Cons: "The flight took forever to land. Pilot said prepare for descent and we stayed in the air for another forty minutes. The air smelled awful. One of the worst flights I’ve ever taken."
Pros: "I was able to purchase extended seat room for a reasonable price."
Cons: "No free drinks or entertainment or anything to help pass the flight time."
Cons: "Staff at check-in counter were not helpful. They were there and they weren't. We were there at the front while two of the counters were ready but didn't call us up. They were chatting with each other instead. We I asked them are they ready to work, she ask me where was I heading. What is the difference?"
Pros: "Price was good and HK to Tokyo times were good"
Cons: "No entertainment on 5 hour flight"
Pros: "Nothing in particular."
Cons: "They don't tell you that 1) you aend up paying more than other airlines charge by the time you add various 'extras'; and 2) you have to go through immigration because they are in another terminal. This means two hours of work, plus I missed my flight because I didn't have 3 hrs. They said my fault."

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.

no charging point. food offering is limited and very much on the budget line. Overall is not satisfying for such a price and duration of flight.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

Scoot refused to change my flight even though I had booked a flexible ticket. MyTrip wanted to charge me an extra $271 for a ticket that was only listed as $217. I complained about this to scoot and they didn't give a shite. So never again will you be getting money from me Scoot. You can Scoot off.
