Frontier has launched the “Friends Fly Free” promotion, a “buy one, get one free” sale for member of its discount program, the “Discount Den.” With the code FLYFREE members get a free matching ticket for select flights any day of the week except Friday and Sunday during the sale travel window. Membership in the program isn’t free; it’s a subscription model for $59.99. However, members get access to the “Kids Fly Free” promotion as well, which provides a free ticket for kids 14 and under with each adult ticket purchase. Plus, Discount Den Savings ($1 – $10/flight) can be used on up to 6 passengers per itinerary, which is great for family travel. But even if you aren’t already a member, you can join online any time; that makes this promotion like getting companion passes for as many flights as you can book before the sale ends, for a single $69 purchase.

The Friends Fly promotion is not nationwide, but it is good on scores of routes in Frontier’s network. The full list of options is on the promotion page. The travel window is between now and June 12; 7-day advance purchase requirements are listed. This is a flash sale, so purchase membership in the Den and your tickets by April 28th (presumably 11:59 PM EST 4/28) to take full advantage.
