What are some of the best travel websites for cheap airfare?

I would like to know websites outside the traditional orbitz, travelocity, and expedia.

Hmm, what about http://www.cheaptickets.com/

i would say first in all check with the airlines directly before going on any other kind of web side must at the time the have better offer and Flight Schedules that others you can also see at http://www.airlineconsolidator.com/ where i find a very cheap fare with air France from NY to Madrid

Have you tried Southwest? Sometimes they have some really good deals if you book it early enough. Try this site out, it might help you out. http://www.dealtaker.com/SouthwestAirlinesVacations-coupon-code-a2069-c.html

spincitytravel.com uses flight consolidators like farebuzz
