Frontier Airlines is offering travelers a chance to save big this spring with the return of its popular ‘Friends Fly Free’ promotion. Available exclusively to members of the airline’s Discount Den program, the deal allows travelers to bring a companion along on select flights for no base fare—only taxes and fees, which start at $18.90 each way. The offer is valid for domestic, round-trip travel on select nonstop routes through May 21, 2025, with flights restricted to Tuesdays, Wednesdays, and Saturdays.
To take advantage of the promotion, passengers must book their tickets by March 24, 2025, and use the promo code “FLYFREE” at checkout. The promotion applies only to new bookings and requires flights to be purchased at least seven days in advance. While the base fare for the companion is waived, travelers should be aware of Frontier’s typical fee structure for seat selection, baggage, and onboard services. Still, for budget-conscious travelers, the promotion provides a cost-effective way to travel with a friend or family member this spring.
The promotion is tied to Frontier’s Discount Den membership, which costs $99.99 annually and offers exclusive access to low fares and companion deals throughout the year. In a bid to further sweeten the deal, Frontier is also including additional perks for bookings made by March 24, such as a free checked bag and complimentary access to its Economy Bundle. The bundle includes a carry-on bag, seat selection, and no change fees, offering added value for travelers who often find low-cost carrier fees adding up quickly.
While the savings are substantial, travelers should pay close attention to the fine print. The offer applies only to nonstop flights and does not extend beyond the specified travel dates. Blackout periods and route exclusions may apply, so flexibility and planning are essential to maximize the benefit.
Frontier’s latest offer comes as airlines continue to compete for leisure travelers ahead of the busy summer season. With travel demand expected to remain strong, promotions like these highlight how carriers are using creative pricing strategies to fill seats and win customer loyalty in an increasingly competitive market.
