Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Excellent meal served with real utensils, cardboard served hot meals instead of plastic utensils and plastic covers. Quick service, friendly and accommodating stewards.

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Wonderful service, planes and interior in great condition, very pleasant experience

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

Transfer within the same terminal and lots of facilities at the airport.

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

The seat comfort, the food and of course the crew, they made you feel welcome and relaxed 😊

We had a 3 hrs delay and they offer McDonalds pineapple pay. They charged us for extra grs of luggage and the experience was not good

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.

Easy boarding and friendly crew. There is no food offered as it is a short flight and no entertainment either…but a good experience overall.

A very nice flight. It arrived on time, and the plane was very clean and the staff was very professional.

Pros: "The crew onboard was friendly, but the check in crew was average."
Cons: "The plane was quite old and there were no beverages except for water."

If you are over 170 cm, i would implore you to select an exit row or front row seat. You will not be able to sleep. Extremely uncomfortable.

My second consecutive experience of flight delay between 1.5 and close to 2hr. Resulting upsetting my biz agenda and additional expenses on local transportation to catch up

Expensive Poor check-in process staff only arrived 2h before boarding which is not a par with international standards Cabin was overly warm No seat Pocket No in seat charging No entertainment No WiFi option Slow cabin service Limited purchasing options Boarding was good Staff were presentable Flight was safe and on time

The flight attendants were not passing out soft drinks. They skipped a lot of rows and passengers were complaining.

The boarding a bit late but overall no drama. Will fly with jetstar again someday for sure.

seat legroom was quite narrow, so i could feel the person’s knees behind me.

Honestly, I Wouldn’t fly Jetstar if I had a choice.

Paid top dollar, and outrageous add ons to get squeezed into an uncomfortable seat with the least leg room possible. Probably best to avoid air travel whenever possible, maybe forever.

They lost my luggage. Doesn't exactly make the experience great.

Leg room is just too short and food costs and is not good quality. But the big issue was they said that my luggage would be transferred to the next flight, so no need for me to exit customs, get a visa and reboard. However that didn't happen and my luggage is still, 2 days later, in Denpasar. So whilst the flight went on time and was fairly average, I think that the cost vs quality is not good enough.
