The terms and conditions are somewhat straight forward as AirAsia’s usual T&C’s go. The redemption does not include airport taxes and related fees. Flights which are eligible for redemption are only direct long haul flights with the D7 and XJ carried code, and excludes flights to Bali, Singapore, Jeddah and Fly-thru routes. Bookings need to be made at least 14 days before the departure date and no flight changes are allowed.
While the bulk of the the D7 and XJ flights are to East Asian countries, we can confirm via this Wiki entry that the D7 carrier code also applies to flights to Australia, New Zeland, Abu Dhabi as well as India. However, as mentioned above, we’re not able to confirm at this point in time whether flights to these destinations will be listed under the unlimited flights pass.
This story will be updated once we have more details on the promo.
