I set some fare alerts on airfarewatchdog.com and have found some great bargains. I had no idea this website existed until a friend emailed me about a $250 round-trip fare to Cabo that she found on this site. If you like to travel and have some flexibility as to destination and/or schedule, it's worth checking out. I just booked a trip on DL that is usually $467, but I got a $152 round-trip fare thanks to a fare alert email. And no, I don't work for airfarewatchdog.com, nor am I being compensated for this recommendation!
