Frontier Airlines has launched a bold new promotion, giving travelers the chance to fly for free while enjoying perks that rival full-service carriers.
The ultra-low-cost airline is offering its Friends Fly Free deal, allowing Discount Den® members to bring a companion at no base fare on select flights. This latest offer builds on Frontier’s $0 Economy Bundle, which includes a free carry-on bag, free advance seat selection, and no change fees—perks that many airlines now charge extra for.
For a limited time, Frontier’s Friends Fly Free deal lets Discount Den members book a second ticket for free, with taxes and fees starting at just $18.90 each way. The deal applies to roundtrip domestic flights booked by March 24, 2025, for travel through May 21, 2025, on select days of the week. To redeem the offer, travelers must book directly through FlyFrontier.com using promo code FLYFREE.
“At Frontier, we’re committed to delivering the best travel value in the sky, and this latest addition to our free perks takes that to the next level,” said Bobby Schroeter, Chief Commercial Officer of Frontier Airlines.
How It Works
Booking is simple. Discount Den® members can sign into their account on FlyFrontier.com, select their desired roundtrip flights, and enter promo code FLYFREE.
The Friends Fly Free promotion must be booked by March 24, 2025, is valid for travel through May 21, 2025, on select days of the week, and is not available on all routes. Click here for more details. The $0 Economy Bundle must be booked by March 24 and is valid for travel through Aug. 18. Additional terms and conditions apply.
Frontier Airlines has introduced sweeping changes to its product and customer service offerings, ushering in ‘The New Frontier.’ Among the enhancements is UpFront Plus seating, an upgraded seating option with extra leg and elbow room in the first two rows of the aircraft. Customers in UpFront Plus enjoy a window or aisle seat with extra legroom and a guaranteed empty middle seat. In the coming months, the airline will introduce free, unlimited companion travel for its most loyal customers. Debuting in late 2025, Frontier will also begin offering First Class seating on every flight, combining unmatched comfort and space at Frontier’s trademark affordable prices.
Frontier continues to innovate with its industry-leading frequent flyer program, FRONTIER Miles, which allows customers to ‘Get It All For Less.’ Members earn miles quickly and get rewarded for each dollar spent on Frontier products. Miles accrue based on dollars spent with a standard 10X multiplier: $1 = 10 miles, with multipliers increasing at every elite level up to 20X. Elite status is attainable at only 10,000 miles and offers perks such as priority boarding, seat selection and free bag(s) depending on status level. Like the airline, FRONTIER Miles is also family friendly, offering easy family pooling of miles making it simple for families to enjoy rewards together. Joining is free.
