Just contacted AirAsia via 1300 number from Australia for help as they have changed the QZ8418 flight times from dps-per for the off season period.
To be told that the Australian 1300 number is only for D7 flights (KL) only from now on, so for example , QZ flights (Indo to Australia) you have to ring an Indonesia helpline to get any assistance beyond the basics.
Just wait till you try this !!!! Aduuuuuuu :)
