AIR ASIA has definitely become my first choice for ECONOMY flight thruout SEAsia !
I have had MANY flights with AirAsia, always Economy... sometimes as a 'normal' passenger, and four flights as an Medical Passenger, using a wheel chair. The wheel chair service is a separate charge, usually 25USD or equivalent. This service makes going thru security, immigration, and customs much quicker and also easier. The drawback ismre debarking the airplane, as there is the WAIT for the whl chr to arrive... the staff has always been pleasant, helpful, courteous -- whether as a Medical Passenger or normal.
I do take my own snacks for the flight !
I do bring a sarong in case it is cool from AC during the flight.
I do continue to choose AIR ASIA, if they fly where I am going.
