The flight left on time and landed early. The attendants were polite and friendly. Thank you

Not good in terms of amenities. For over 6 hours they don’t even provide complementary drinks or snacks-forget about dinner or lunch.

Very good, it would be good if payment for drinks could be accepted by card too.

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.

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

Very few crew meant that we had to wait almost 2 hours just the get a drink!

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

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.

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.
