The most publicized component of the program is the Kids Fly Free promotion. Under specific guidelines, one child aged 14 or younger flies free per paying adult member on the itinerary. For a family of four with two qualifying children and two adults, a single round trip can theoretically yield hundreds of dollars in base fare savings.

The limitation lies in date and route availability. Frontier restricts Kids Fly Free to select round-trip domestic flights, heavily restricting popular holiday windows, spring break surges, and peak summer weekends. Tuesday and Wednesday flights offer the widest availability, while Friday and Sunday departures almost universally exclude the perk.

Beyond children, the companion booking rules offer substantial flexibility for general group travel. A Discount Den member can book up to 9 passengers on their reservation, extending the exclusive discounted rate to every individual on that itinerary. You do not need children to extract outsized value; organizing a weekend trip with friends easily pays for the annual subscription in a single transaction.
