I actually bought our very first tickets to Belize through Sky Auction. Didn't get a great deal... but I guess that's my fault for bidding too high.
I was a novice then. Their price from Houston is pretty good, but then you have to tack on the extra $$ for wherever you live, and that brought it right up there... over $700.00. I just got a ticket for $569. from my travel agent. This is from Portland, Oregon which is about the most expensive place in the U.S. to get a ticket to Belize from!!
I'm considering moving to Houston just because it is closer to Belize. <just kidding>
