Cheap flights to Thailand between end of November to February
I've been trying to organise a trip to Thailand from Sydney for a while now, however due to me and my friends having commitments we've only recently finally managed to find dates we can can all agree on.
What companies tend to provide cheaper flights? Should we buy now, or wait later?
We are looking for the cheapest flights possible as we would prefer to spend more at the place.
Thanks and any advice is appreciated.
