If you've ever heard the excuse from friends that they can't afford to travel, now you can offer them a free flight on Frontier Airlines if they take a trip with you. This buy one, get one free promotion is exclusive for Frontier's Discount Den members and is valid for nonstop domestic travel on specific dates.

Update: After several months of hiatus, Frontier has re-introduced this offer for purchase through March 23, 2020. (Travel through May 31, 2020).

How to Book Free Flights for Friends on Frontier Airlines

To book, you must become a Discount Den member, if you aren't already, which has a $59.99 annual fee. Other perks of membership include discounted fares for up to 6 passengers on the same reservation and early access to booking flights when Frontier extends its booking schedule. You can sign up to be a member during the booking process and the free ticket for your friend may completely offset the cost of membership.

Travel Availability

Use promo code FLYFREE when booking for at least 2 adults on FlyFrontier.com for travel within the following dates and specific days of the week.

  • Promo Code: FLYFREE
  • Travel Period: Now through May 31, 2020.

Make sure you have selected at least 2 adults when booking or you'll get an error message. And good news for groups! This buy one, get one offer works for up to 6 people. You'll get a free ticket for every adult ticket purchased. Buy two, get two free, or buy three, and get three free. Only one Discount Den membership is required.

You may have to click around to find available dates since Frontier operates about half of its route network on just a few days each week.

Sale Period

Tickets must be booked by 11:59 pm ET, March 23, 2020. Similar deals were offered multiple times in 2019 and may be offered to Discount Den members again in the future, but there is no guarantee.

Frontier's fares only include one small personal item. Checked bag fees start at $30 each way when purchased during the initial booking. Larger carry-on bag fees start at $35 each way.

Seat Assignments

Frontier's fares do not include specific seat assignments. Seats will be assigned at random upon check-in if you skip the seat selection step when booking. You may pay a fee to choose a specific seat.

Alternate Fares

Frontier offers the Works bundle, which can be added to any flight during the initial booking. It includes a standard carry-on bag plus a personal item, one free checked bag, seat selection (including stretch seating), priority boarding, flight flexibility, and refundability. This is a value if you want all of these amenities, but chances are you can get away with just adding what you need a la carte for cheaper.

Is there a Catch?

Of course, bag fees and other travel add-ons such as choosing a specific seat are extra, but to my surprise, this buy-one-get-one-free promotion actually discounts the entire airfare including taxes and carrier-imposed fees like Frontier's online booking fee. This fee, which is labeled a "carrier interface charge", along with taxes can often make up the majority of the ticket price on Frontier. The fact that you'll only pay taxes and booking fees on one ticket for 2 travelers makes this an incredible deal.

Flying with friends is always more fun so if you're looking to take a trip with a companion or a group of friends, check out how much you can save using this promotion. Frontier often has the lowest fares in the markets where it flies. Major carriers usually compete with slightly higher fares, but the added bonus of free flights for friends on Frontier may steer you to give this ultra-low-cost carrier a try. Save on bag fees by traveling light and combining everything you need in as few bags as possible.
