Guys don't use credit card use bank direct debit, Even I have credit card i don't use it i'm using maybank2u to book, Air Asia will charged you additional charges. Remember one time their bank direct debit got problem so I had to use credit card and they charged me extra RM10.00 or 20.00 perticket I forgot what they called convenient charges imagine if you buy 5 tickets how much you have to pay extra?.....
