Hi everyone... first, wanna say great and informative thread here!

I went through most of the posts, but can't seem to find some info I need -- what kind of hidden surcharges can I expect for flights to Bangkok? I'm planning a trip next year in March/April. I believe Air Asia is having their super-cheap tickets promos that start from 1 April, but it doesn't include taxes and fares. How much would these come up to? And what about fuel charges?

Hope someone can help.
