It's no secret that all of us here at AutoSlash are travel addicts.
On top of renting dozens of cars a year and staying many nights in hotels, we also fly tens of thousands of miles all over the globe. (We justify it to ourselves by saying we have to be travel experts in order to provide the best service to our customers, but really we all just suffer from an acute case of wanderlust.)
Much of my travel has been on cheap airfare sales or even outright mistake fares. I don't think I've spent more than $500 (round-trip!) to cross any ocean in the last nine years (not counting the miles I've redeemed to fly international first class, of course).
While there are all kinds of sources out there to help us find those cheap airfares—one of the ones I've found the most productive is TheFlightDeal.com, but there are lots of others we'll cover some other time—I always gravitate towards one place to book my flights: Priceline.
