Be careful -- you can always do much better than the fares quoted by Expedia for longer haul trans-oceanic flights. As an example, the lowest fare quoted on Expedia is $2999 (CAN) from Calgary to Doha (Middle East) with a maximum 2 month stay. I can get this fare from my local travel agent and still get frequent flier miles for $1600 (CAN) with a maximum 3 month stay -- more flexibility and almost half the price. The lowest fares on Expedia and others are generally ok for domestic but even there sometimes the airlines have their own specials which are worth checking.
