Quite a decent economy fare to Bangkok with Thai, a 4 star rated airline.
Over $1000 for the 'budget' AirAsia, and Student Flights is asking for $891 for flights to Bangkok with Thai. So a pretty cheap trip over to Thailand on a great product.
Catches are that you have to be a student or under 26 or 31 (Youth). Fares for everyone else are pretty average, starting from $889 return. And, "This offer is valid when you purchase either 2 nights accomodation or any insurance policy from STA Travel." so maybe book a couple of cheap nights in Bangkok with STA. (Thanks Car-la-la)
Travel periods are: 01/05/2012 - 30/09/2012
i believe there is another catch … to qualify for these flight prices you need to book travel insurance through STA or a few nights accommodation through them (both over priced - but great flight price all the same!!)
