JetBlue is bringing back its popular All-You-Can-Jet pass that allows customers to travel to an unlimited number of cities over a one-month period for $699. The pass is valid seven days a week for flights between Sept. 7 and Oct. 6, JetBlue Airways said Tuesday. It will also offer a pass that excludes travel on Friday and Sunday for $499.

Last year, the first time the airline offered the full-travel pass, the price was $599.

The passes are being issued during a traditionally sluggish travel period wedged between the summer vacation and winter holiday seasons.

The passes are for sale through Friday, but there is limited space. The passes sold out in two days last year.
