How to get a year's worth of flights for $599

Frontier's flight pass allows for unlimited last-minute flights for $599 for a year.

Have you cut down on travel over the past couple of years and are wanting to make up for lost time? Always planned to see more of the US? Take a trip of a lifetime around your home country? Enter Frontier Airlines, and its new unlimited annual flight pass -- for just $599.

That's the introductory cost for what's been named the GoWild! Pass. Unfortunately, it's not available to those wanting to visit the US on a bucket list trip -- it's only available to those aged 18 and over, who reside in the United States.
