Unlimited flight pass valid for trips between Sept. 8 and Oct. 8.
NEW YORK (CNNMoney.com) -- JetBlue Airways will offer an "all-you-can-jet" pass for $599 in which passengers can book an unlimited amount of flights within a one-month span, the airline said Wednesday.
Pass holders can fly to any of JetBlue's (JBLU) 56 destinations between Sept. 8 and Oct. 8, with no seat limitations or blackout dates, the company said in a release.
Airline equities analyst Bob McAdoo, of Avondale Partners, said he "has never seen a promotion like this before."
In fact, Air Canada had a similar promotion in 2007, where it offered an unlimited flight pass starting at $1,657 per month.
Still, with JetBlue flights already slashed as low as $100, customers might have to fly 6 or 7 times in a month before they break even.
"This is a way to get people to pay attention, with publicity that doesn't cost the company much," McAdoo said. "They're doing this at a time when there are probably a lot of seats available anyway."
Customers must buy the $599 pass by Aug. 21, and they can book flights within three days of the departure date. All travel using the pass must be booked between Aug. 12 and Oct. 5.
