I cannot remember a flight without delay
I cannot remember an AirAsia flight in the last year without signifikant delays. Mostly 1 to 4 hours. It is cheap but you waste time permanently and it is not trustable if you have connection flights. Just sitting in Don Muang waiting for my 1,5 hours delayed flight to Chiang Mai. Btw.: almost every AirAsian flight has delays. Delays are a rule with this airline not an exception.
