Just as it did last year, JetBlue has sold out of its all-you-can-jet pass within days of its announcement. Of course, the airline doesn't announce how many passes it actually makes available for the promotion, so we don't know if they went like hotcakes or more like molasses. Both the $699 and $499 restricted versions are now gone.

Last year, the passes sold out a day ahead of the purchase deadline. This year, they sold out four days in advance of the original deadline, Monday Aug. 23.

And just like that, JetBlue has scored three rounds of free publicity in a week: pass announcement plus two sell-out announcements. It sure beats press that tells the world that your flight attendants are so fed up that they're using your aircraft as their own private bouncy castles.
