Today Only! Penny Fares (plus tax) on Frontier; Fares Starting at $24 Round-Trip

Book quickly! Frontier has dropped around 95 routes (counting both directions) to just $29 round-trip for spring travel. Many new routes are offered in this one-day sale and will be much less than the competition. Fares can be bought one-way for $15 on well over 100 routes.

Availability is limited so you must be somewhat flexible to find the lowest price. Travel days will vary by route, but generally are available for travel through May 16. Many routes have limited frequencies so be sure to check out the specifics in the fare details on your route.

As you can see in the screenshot below, these are essentially FREE airfares. You are only paying mandatory taxes and fees. Frontier even eliminated their online booking fee for these fares so this is the absolute lowest price you can get on these flights. Bag fees are extra unless you can travel with just a small backpack.

Tickets must be booked by 11:59pm, tonight, April 19, or before seats sell out.

Most of these fares will work in reverse and there are many more routes as well. Check flights from your city. Keep in mind that Frontier charges extra for any bags larger than a small personal item (small backpack, large purse, etc.). Pack super light to get the lowest price. Checked bag fees start at $25 each way. Larger carry-on bag fees start at $30 each way.

Take advantage of these low fares while you can. Frontier is known for starting new service in random markets and ending the service quickly if it doesn't turn a profit. I'm hopeful that most of these new routes will stick around, but it's likely that many of them will only be operated for one season.
