Kids Fly Free? That’s Crazy!

Flying Frontier makes it easy to get great travel deals for your family, and we’re making it even easier for your flock to fly by letting Kids Fly Free. FREE. And we aren’t just talking about the small-enough-to-sit-on-your-lap kids. We’re including the tall-enough-to-ride-the-big-rides kids, the mom-I’m-not-a-baby-anymore kids, or the oh-my-gosh-they’re-almost-driving kids. All kids 14 and under can fly free on select flights with the purchase of a Discount Den® member fare.

Free flights for kids means you and your family can travel more often - that means more time together gathering new experiences and more visits to grandma.
