Some websites to look, as I've posted in the past:
Cheap Flights, Airline Tickets, Cheap Airfare & Discount Travel Deals - Kayak.com (Comprehensive search site - usually the lowest price can be found here)
vayama | international travel solved (Another travel site that sometimes has low prices that aren't found on Kayak.
