Go on, take the month off. JetBlue recently announced a $599 "All you can jet" pass that lets you travel as much as you want, anywhere JetBlue flies. You have from September 8 to October 8 to fly from the mountains to the valleys, from sea to shining sea, and every other cliché you can hum. You must sign up for the pass by August 21. JetBlue says it has the right to suspend the sale of the passes earlier than that, however, so hurry if you're interested. 

As our colleagues at The Consumerist note, however, it may not be the deal it looks like, considering that many JetBlue flights, all sold as one-way legs, are fairly inexpensive to begin with. For instance, at this posting the airline is offering one-way flights as low as $99 from Ft. Lauderdale to Long Beach, Calif. You'd need to fly three round trips in one month before you'd approach breaking even. 

Taxes and fees are included in the deal; additional taxes and fees only apply to Puerto Rico and international travel. But the rules state that Jet Blue will slap you with a $100 penalty, among other restrictions, if you fail to show up for a flight.
