Frontier Airlines Unveils Game-Changing Friends Fly Free Promotion for Discount Den Members

Published on March 19, 2025

Who doesn’t enjoy being the friend with benefits, especially when those benefits include a free trip with your travel buddy? Frontier Airlines is offering a deal that makes flying with a companion even more affordable. After announcing the $0 Economy Bundle, which includes perks like a free carry-on bag, free seat assignments, and no change fees, the airline has taken it a step further with the Friends Fly Free promotion.

For a limited time, Discount Den® members can book a trip with Frontier and receive a free companion fare. This offer, which covers taxes and fees starting at $18.90 each way, is perfect for those who want to travel together at a discounted rate. It’s an exciting way for Frontier to continue enhancing the customer experience with unbeatable savings.

Here’s how it works:

• Free Base Fare for your companion
• Free Carry-On Bag
• Free Advance Seat Assignment
• Free Changes

Booking is easy for Discount Den® members: simply log into your account on FlyFrontier.com, choose your roundtrip flights, and enter the promo code FLYFREE.

This promotion must be booked by March 24, 2025, and is valid for travel through May 21, 2025, on select days of the week. It’s available on select routes, and the $0 Economy Bundle offer must also be booked by March 24, with travel valid through August 18, 2025. Additional terms and conditions apply.

As part of their ongoing improvements, Frontier Airlines has introduced several changes to their services, including UpFront Plus seating with extra legroom and elbow space in the first two rows of the aircraft. Frontier is also planning to roll out free, unlimited companion travel for its most loyal customers by the end of 2025, and the introduction of First Class seating on all flights later that year, making it easier for passengers to enjoy luxury at affordable prices.

Additionally, Frontier’s FRONTIER Miles program continues to reward loyal customers with miles for every dollar spent. Members earn miles quickly, with the opportunity to earn up to 20X miles at elite levels. Elite status starts at just 10,000 miles, and offers perks like priority boarding, seat selection, and free bags. Plus, families can pool miles, making it easier to enjoy rewards together.
