How to Fly for Sooper Freaking Cheap!!
I found this deal by AirTran called "X-Fares"
You just show up at their ticket counter and say, "Hey! I wanna get to _ with your X-Fares program!" And they charge you only $70 per leg.
I showed up in Boston 40 minutes before a flight, and got to San Francisco that same night, in two legs, with no delays. Do it! Travel the country!
Check out their blackout dates before you go. Some ("long haul") legs cost $100 instead of $70.
