Here's a new one: fly your fill for $599 with JetBlue's new offer. It's an All-You-Can-Jet pass which gives you, dear flier, unlimited air travel anywhere they fly between Sept. 8 and Oct. 8. That's 30 days of you flying high at $19.96 per day. (taxes included). The pass is on sale through Aug. 21.

JetBlue begins flights to Boston from BWI on Sept. 9. You can connect from BOS to Los Angeles, San Diego, Seattle, Denver, New Orleans, Bermuda, San Juan, PR, and more. You can also fly from Dulles to a host of other destinations, including Florida and Jamaica. 

Once you decide on this course, you'll have to sign up for the TrueBlue loyalty program - frankly if you spend a month on a plane, you will have earned mad miles so you might as well join the club. There's a boatload of other rules and technicalities about booking your flights. The two most important in my mind being 1) you can only book one flight per city per day and 2) they won't tolerate "no shows" - you'll be charged a $100 fee and your pass will be suspended - you'll have to pay before you can book another flight.

All in all, sounds like a good deal if you've got time to jet. And you may want to get in on this offer early since JetBlue reserves the right to end it at any time. Although the travel is unlimited the number of passes is probably not.
