Frontier Airlines is having a sale on flights around the U.S., with deals starting at $20.

The cheapest flights include $20 fares between Atlanta and Cincinnati, Greenville and Orlando, Oklahoma City and San Antonio, and more. For $24, book a flight between Austin and Tampa, Jacksonville and Austin, or to Orlando from several different cities.

Depending on where you're flying from, there are flights starting at $29 to Frontier's homebase in Denver. Once there, you can enjoy one of the longest periods of fall colors in the U.S. thanks to Colorado’s five different climate zones. You can not only enjoy the city but also the nearby national parks, like Rocky Mountain National Park, which is great to visit in September, October, or November.

There are tons of other cheap flights so check Frontier to see what's available from your home airport. The sale runs through Friday, July 20; travel dates go from mid-August to mid-November.

Frontier is a budget airline, with extra fees for things like seat selection and checked bags. Check what fees you may incur for the service you want before booking to make sure you get the deal you expect.

And if you're feeling like what you really want to book is a trip to the Caribbean, JetBlue is also having a sale through Friday with flights to Aruba, Jamaica, Puerto Rico, Barbados and many, many more starting at $59.
