Air Asia is the way to go if possible, but I would consider another destination, Bali the toilet bowl of Asia
If you have ever been there you would know what I mean, for the life of me I cannot see the fascination in that place.
You can get to Thailand for not much more. I saw a notice in the crew room yesterday for 7 nights in Phuket for $99, the catch was you had to spend 90 mins at a presentation, I suspect a time share thing. Bit of a pain but sit listen and say thanks but no thanks after the presentation then get on with you holiday. I suspect,, don't know, the accommodation would be ok as they are trying o sell it o you.. No point putting you p in a dump and then putting pressure on you about time share.
Otherwise agoda . Com. I find then very good.
