Kids fly free on Frontier Airlines — even young teens? Yep. You read it right. Frontier has launched a ‘Kid Fly Free’ promo for children 14 and younger traveling with an adult. But there’s a catch. You have to be a member of the airline Discount Den club, and you have to move fast since the promotion ends February 12.

Committed to Families

“Kids Fly Free shows our continued commitment to being America’s affordable and family-friendly airline,” said Barry Biffle, President and CEO of Frontier Airlines. “We’re the only airline going all out for families in this way – it’s exactly what we mean at Frontier by Low Fares Done Right.”

Join the Club

First, you’ll need to join the the Discount Den club, if you aren’t a member already. The club costs $59.99 per year, but there are some cool benefits, including the Kids Fly Free program. You also get access to Frontier’s lowest available fares — for up to six people on your travel itinerary. Sound good? Check out the Discount Den deals.

Book Your Flight

Next, book your flight on flyfrontier.com. Remember, for every adult booking a ticket, one child can fly for free. Just chose a qualifying flight – marked with the Kids Fly Free logo beneath the Discount Den price – and keep your fingers crossed that you can nab a seat! These promotions usually sell out quickly.
