Frontier Adds 6 New Routes From Atlanta, Including International Destinations

Frontier Airlines is closing out 2025 in a big way, with several new destinations added to its route map. The airline is adding 6 new routes from its hub in Atlanta (ATL), including several popular international destinations.

“There’s a lot to be excited about as the new year approaches — from our expanding network to rolling out our First Class experience — and we’re thrilled to offer travelers even more affordable flight options from Atlanta as we continue to grow,” said Josh Flyr, Frontier’s vice president of network and operations design.

Let’s take a look at Frontier’s new routes.

New Frontier Routes

Frontier Airlines will roll out 6 new routes from Hartsfield-Jackson Atlanta International Airport (ATL) this month, just in time for the holiday travel season.

Here’s the list of Frontier’s other additions from Atlanta:

All told, with the addition of these new routes, Frontier will serve 61 destinations nonstop from Atlanta.
