This is not an early April Fool’s joke. Via a new offer, kids can really fly for free on Frontier Airlines. Sometimes. Are there caveats to this too-good-to-be-true sounding offer? Yes but, at the end of the day, your child aged 14 or under really can fly for free with you on Frontier, without sitting on your lap or needing a Companion Pass.

Kids Fly Free With a Frontier Discount Den Member

In order to have your kids fly free with you on Frontier, you need to be a Discount Den member. This membership costs $59.99 per year, but it was a pretty good deal for Frontier customers even before Frontier added “kids fly free: as a perk. Being a Discount Den member means you get access to Frontier’s lowest prices not only for yourself, but for up to six on the reservation. In other words, it can more than pay for itself in one family trip. Discount Den savings vary, but saving $10 per person, per direction, is common — resulting in $80 in savings on a family of four’s round-trip flights. Fly more throughout the year, or with more people, and save more. Discount Den members also often get access to Frontier schedule extensions before non-members.

What’s the Catch?

Beyond the Discount Den membership requirement, kids fly free is only valid on certain dates to domestic destinations. The valid dates are listed below for as far out as the Frontier schedule currently extends. Generally speaking, the kids fly free offer is often valid on the cheapest days to fly: Mondays, Tuesdays, Wednesdays and select Saturdays, though generally not on all of those dates in a given week.

More valid dates would be great, but once the kids are out for the summer, lots of these dates could potentially work. Take a long weekend away in June on Saturday to Tuesday or Wednesday, or take a whole Saturday to Saturday trip. Heck, even if you can only line up a trip to fly the kids free in one direction, that’s still more free flights than you’ll find on most airlines.

Frontier Kids Fly Free Dates

  • February: 12, 13, 19, 20, 26, 27
  • March: 5, 6, 12, 13, 19, 20, 26, 27
  • April: 2, 3, 9, 10, 16, 17, 23, 24, 30
  • May: 1, 4, 7, 8, 11, 14, 15, 18, 21, 22, 29
  • June: 1, 4, 5, 8, 11, 12, 18, 19, 25, 26
  • July: 9, 15, 16, 22, 23, 29, 30
  • August: 5, 6

More “kids fly free” dates will be announced each time Frontier extends its flight schedule.

One kid can fly for free for every adult on the ticket. Families with both teens and little kids may appreciate that anyone 15+ on the reservation can trigger a free kiddo ticket. So, a family of two adults, one 16-year-old, twin 8-year-olds, a 5-year-old and a Discount Den membership could pay for three tickets and have the three youngest kids fly for free.

Families with babies will love that infants are eligible for this offer, too. Your “lap infant” can have his or her own seat and still fly for free.

Are There More Catches?

We’re dealing with an ultra low-cost carrier, so skepticism is always healthy. I can’t find any more real catches than what was already mentioned and the deal can be booked as long as there are two seats for sale on the flight. But there are some caveats to note. First, this is not valid retroactively, so this would only work on future bookings for Discount Den members. Also, bookings must be made on and kids fly free are only valid on initial bookings. Changes to the ticket result in the loss of the promotion. Of course, you can ramp this up by paying for the adult tickets on with a card like the Barclaycard Arrival Plus World Elite Mastercard or Capital One Venture Rewards Credit Card and then use miles from those cards to offset the charges.

Any ancillary add-ons, like checked bags, full-sized carry-on bags, stretch seats and seat assignments, are still charged per person. Kids don’t get those sort of add-ons for free — even if their fare is free.

Seat assignments cost extra.

But — I’ll Have to Fly a Low-Cost Airline

Let’s be clear, Frontier is not perfect. If you don’t spring for stretch seats, you will be a bit squished. There’s no in-flight power or Wi-Fi, and Frontier’s on-time arrival stats can stand to improve as they still lag behind the national average. But — pack your patience, your backpack, your kids, your own snacks and drinks and you can hit the sky for less than on pretty much any other airline. My family travels in lie-flat seats and on ultra low-cost carriers, so mix and match high- and lower-end travel, depending on what’s best for each trip.

I was already impressed with Frontier’s 2018 changes to become a family-friendly airline even before this promotion, but now I’m a loud and proud Frontier fan. The airline currently has one of the best frequent flyer programs in the US for families (yes, really), allows family pooling of miles for elites and card holders, has a credit card that you can use to spend your way to elite status, offers cheap fares as low as $15 to $20 and has a growing route network with over 100 destinations.

Bottom Line

You will have to read the fine print on this one, but “kids fly free” is such a novel offer (at least in the United States), that I’m not all that bothered by the details and limitations. Frontier is making it possible for families who might otherwise not have been able to afford to fly to hit the sky and explore the country. Or, perhaps they are enabling families to take that second trip per year, or second trip per summer, or whatever the case may be. This is not a one-time promo but a new long-term offer from Frontier.
