"All You Can Jet" with JetBlue

Fly as much as you want for a flat fee on JetBlue from Sep 7 to Oct 6:

JetBlue, which pioneered the fare concept last year with its "All You Can Jet" pass, is offering fliers two options this year. The most flexible — which costs $699, $100 more than last year — lets customers book a seat on any available flight from Sept. 7 to Oct. 6. For $499, customers can fly any day but Friday and Sunday to any of its 61 destinations.

Sun Country, a small airline operating out of Minneapolis St. Paul, is offering a similar promotion.
