More details finally released. Could be a great deal, even with airport tax being additional. Amongst the caveats, the one that worries me:
Please take note:
•Credit can only be redeemed for your base fare.
•Any airport tax and add-ons such as check-in baggage, inflight meals, seats and travel insurance are to be paid separately.
•Each flight will need to be redeemed at least 14 days before departure.
•Each route can only be redeemed once using an AirAsia Asean Pass.
•Travellers must be 12 years old and above.
•Flight redemption is limited and subject to seat's availability, it may not be available on every flight or day, ie weekend, public holiday and school holiday.
•All GST and taxes are payable only upon flight redemption and not charged on AirAsia Asean Pass
As far as I can see, it's not possible to search for redeemable flights w/o already having the pass
