I am surprised at Peter RS’s experience with Air Asia rescheduling. I have had flights rescheduled and the airline had automatically issued an email titled URGENT : AirAsia Flight Reschedule Notice. The email clearly sets out the old and new flight times and provides options by clicking buttons in the email to accept the change and reserve seats, or to free of charge move to a different flight between same departure and destination points on same or a different day, or to request full credit which is applied to your Air Asia account and can be used against further bookings up to 730 days from the date on which the credit is issued. I found the process to be particularly well communicated, user friendly and actually much better than the mechanisms many full service airlines have for dealing with changes and cancellations.
