Where are the cheapest places to get airline tickets?
I've found these websites to all be comparable:
http://www.orbitz.com http://www.priceline.com http://www.travelocity.com
Many of them index the same discounted flights. Also, if you have a flexible date for travel, Priceline will let you name your own price, which can be a great deal.

Good sites to get airline tickets. My parents use them every time we go to Japan :D
