Book quickly! Frontier has dropped around 50 routes (counting both directions) to just $29 roundtrip for late summer/fall travel.

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 between August 14 and October 3. 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 the 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, on August 1, or before seats sell out.

Greenville to Orlando $24 roundtrip
