Frontier has dropped 36 routes (counting both directions) to just a penny plus taxes. The breakdown actually shows a $0 airfare. After taxes, fares start at just $24 roundtrip.

Availability is limited so you must be somewhat flexible to find the lowest price. Travel days will vary by route, but these rock bottom fares are generally available for travel through October 3, with a 7-day advance purchase required. 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 15, or before seats sell out.

Greenville to Orlando $24 roundtrip

Memphis to San Antonio $24 roundtrip
