The offer mentioned below has expired and is no longer available.

Frontier Airlines is bringing back its popular “Friends Fly Free” promotion, allowing Discount Den members to book a companion ticket for just the cost of taxes and fees.

This limited-time deal applies to select round-trip domestic flights through May 21, 2025, but there are important restrictions to keep in mind. Additionally, you need to book by March 24, 2025.

If you’re looking for a budget-friendly way to travel, here’s everything you need to know before booking.

Frontier’s ‘Friends Fly Free’ Promotion — The Details

This promotion is exclusively available to members of Discount Den, Frontier’s annual membership program that costs $99.99 for the first year. Discount Den offers access to lower fares, special promotions, and even the airline’s Kids Fly Free perk on eligible flights.

To take advantage of this deal, members must book a domestic round-trip ticket and apply the promo code “FLYFREE” at checkout. The companion’s fare will be covered, leaving only taxes and fees to be paid — starting at $18.90 each way.

However, there are key limitations:

The promo is valid only on Tuesdays, Wednesdays, and Saturdays.
Flights must be nonstop and booked at least 7 days in advance.
The offer is valid for bookings made through March 24, 2025, at 11:59 p.m. EDT.
The companion must be traveling on the same itinerary as the Discount Den member.

Eligible routes include flights to and from major airports like Atlanta (ATL), Seattle (SEA), Las Vegas (LAS), Orlando (MCO), Chicago Midway (MDW), Baltimore (BWI), Tampa (TPA), Phoenix (PHX), San Francisco (SFO), Miami (MIA), Denver (DEN), and Palm Beach (PBI). If your travel plans align with these dates and locations, this could be a solid deal, but the restrictions mean it won’t work for everyone.

Bottom Line:

You’ll need to book your flights by March 24 and travel by May 21 to take advantage of this offer. Additionally, you’ll pay taxes and fees to bring your companion, and travel is only permitted on certain days of the week.

Is It Worth It?

Bringing a friend or special someone on a flight with you for just $18.90 sounds awesome. The cost could be slightly higher than that, depending on routes and dates, but the potential value looks attractive at first.

However, it’s worth re-emphasizing the restrictions tied to this promotion. It’s only available to Discount Den members, not the general public, and has a short travel window. The booking window is extremely short, and only certain days of the week are eligible for travel. That’s a lot to navigate. Make sure you take that into account.

Hot Tip:

Frontier has other promotions for free checked bags and economy bundles right now. These are also worth considering.

Final Thoughts

Frontier’s “Friends Fly Free” promotion is a great way to save money, but it comes with significant restrictions, including limited availability and the requirement of a Discount Den membership. Still, when combined with the airline’s other promotions — like free checked bags and Economy Bundle perks — this deal can offer solid value for budget-conscious travelers.

If you’re considering booking, make sure your travel dates and destinations align before the March 24 deadline.
