This isn't meant to shortcut the travel agents, but I recently bought a ticket to BZE through
http://www.priceline.com and saved 47% over the best rate I could get through a travel agent or other online ticket site. I'll be traveling in October, and thought I had nothing to lose over trying to book through a conventional method. I made my bid and got a confirmation within an hour and Continental Airlines accepted my bid for nearly half their current "discount rate". Just thought I'd pass on another option.
