When you change your booking online you will be charged a change fee of 80 Malaysian Ringgits PLUS the difference between your old fare and the new fare.
See: http://www.airasia.com/site/my/en/page.jsp;jsessionid=004771E46B367A3B6E3C2A7B7A5FDBE4?name=Fee+Schedule&id=e1a7f88f-ac1e2082-17ccb2f0-b6bdf4fa&nav=0-2
The cost of changing dates can be huge with Air Asia. Particularly, if your first booking was a very low promotional price eg $A77 and you are forced to accept a far more expensive fare for the second booking.
