JetBlue Airways Corp. in a bid to fill up empty planes has launched a $599 fly pass promotion allowing passengers unlimited airplane rides for a month valid between September 8 and October 8.

The $599 includes taxes for domestic destinations but not international taxes. Travelers are given a choice of 57 cities and more than 600 daily flights for an unlimited number of times for one month.

JetBlue's network includes the U.S. and leisure destinations in Mexico, Costa Rica and the Caribbean. Travelers are required to book by August 21 the date when the offer ends.

If you book a flight but fail to show up, JetBlue will suspend your pass until you pay a $100 penalty.
