If saving a few dollars mean so much to you and thats all you can afford, yes Air Asia will get you to your destination.

I only fly TG and PG domestically in Thailand these days. I have flown enough with Air Asia before to realise that my dignity is worth a lot more than the few dollar savings. I won't even fly them even if its free, so I actually find it amusing when posters discuss about how much cheaper the fares are.
