Frontier is offering customers an 'all-you-can-fly' pass for unlimited travel this summer starting at $399

• Frontier Airlines is selling an "all-you-can-fly" pass starting this summer, called "GoWild!"
• The pass offers customers unlimited flights to all of Frontier's destinations for five to 12 months.

Frontier Airlines is officially debuting an unlimited flight pass to customers.

The low-cost airline announced the launch of "GoWild!" on Tuesday, an "all-you-can-fly" program that Frontier customers can purchase for as little as $399 for a five-month summer pass to $1,299 for an annual membership, according to a press release.

The pass offers several perks, including unlimited flights to all of Frontier's destinations for 12 months and the ability to travel on over 300 days per year, per the release.

The summer pass begins May 2 and ends Sept. 30 for a limited-time price of $399 per year, though will retail for a regular price of $999. The 12-month pass retails for $1,999, but is currently on sale for $1,299 per year.

As part of the program, members must book their international trips at least 10 days before flight departure and at least the day before for domestic travel. They'll be charged $0.01 in airfare, and tickets don't include bags.

Although it appears the pass will be available to use on most days of the year, there are blackout dates throughout both 2023 and 2024 that mostly fall around holidays, according to the official site.

Frontier announced the program in October 2022 and gave its loyalty members first access to join a list to receive more information about the new pass, including pricing, which the airline said will be a "wildly discounted rate." The passes are limited, non-transferable, and on a first-come, first-serve basis, according to the airline.

The Denver-based carrier is not the first airline to come up with travel passes. Southwest Airlines, for example, currently has a "companion pass" that lets qualifying frequent flyers bring a travel buddy with them on their flight, and the additional seat only costs taxes and fees.

Meanwhile, JetBlue Airways previously offered an "all-you-can-jet" pass in 2010 that gave buyers unlimited flights for 30 days for $699, with a cheaper offering of $499 that excluded Friday and Sunday travel.
