if your looking for value, just pop into trailfinders or ring them and ask for the cheapest possible flights. i do this every year. got flights to china (retrun) for 600, flights to japan then onto thailand for 1k (return). You can check online, but for the cheapest flights your normaly looking at making more then one or two connections, but the savings are well worth it.
not afliated with the Trailfinders in any way, but they will make sure you get the cheapest flights.
