If you are a frequent flyer, one airline company may have just the deal for you.
JetBlue Airways is offering a $599 program that will allow flyers "unlimited travel" to and from its more than 50 cities from September 8 to October 8.
Pass holders will have no seat restrictions or blackout dates, and can book flights as late as three days prior to departure. Travel must be booked between August 21 and October 5, and customers have to purchase the plan no later that August 21.
