UCB travel agent: Carlson Wagonlit travel

Favorite flight finders

skyscanner.com– Cheaper/more airlines than any other aggregate service I've found; saved me when I messed up a plane ticket and needed to buy a new one within 24 hours of departure.

Kayak

ITA software matrix– What travel agents use to search for flights, but you can't buy them directly off of here
