AirAsia just openend booking for Kunming to KL with a special promotion price (203 RMB).
However on Airasia website, I am unable to find a flight under 800 until february and the cheapeast is 689 RMB in next April...

Is that again a fake promotion or anyone had more luck finding cheaper flights.

I would like to travel to Indonesia before January 2013...

well that's how they promote. they may have had a flight at 203 kuai, but of course that will be immediately be booked within an hour of announcement (same in Chengdu when they started out). So nothing unusual here. Also pay attention to the booking conditions (check if date change, cancelation, name change are possible).
