Skyscanner will list destinations (cheapest first) if you to put in your outbound airport, dates and person count (just leave the To: field blank). It’s great for figuring out where you can afford to go! Thanks to my wonderful friend Erika for telling me about this site!

I put in NYC (for any NYC airport) and listed some dates and number of people and BOOM – cheap(er) destination ideas!
For another great travel site, see my recent micro-post on SeatGuru!
