A while ago I signed up to test out Farecast an airfare predictions engine. Today I got an email that makes me very happy:
Farecast is happy to announce that airfare predictions for flights out of Philadelphia (PHL) are now available at Farecast.com.
Actually they now have 55+ cities to choose from – which is a lot more than they had when I first signed up. If you have to travel a lot this fall for conferences you might want to give this site a look.
