In recent months and years, the booking windows for the really rock-bottom Air Asia sales seem to be going further and further out into the future. They might do a sale, for example, for travel dates fro 3 months to 6 months from now.
It used to be that you could be much closer to your date of travel and still get a deal, but that has become harder to do in recent years. The exception might be certain domestic routes in Thailand like BKK-UBP, as there's a real fight on for those. I prefer Nok Air there, though...not as bad a fee-ing frenzy.
