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.

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.

The new routes include 1 domestic and 5 international destinations, including weekly service to St. Martin (SXM) and Nassau (NAS), Bahamas. Those flights started on December 6 and December 13, respectively.

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

If you’re considering booking any of these new routes, make sure to use a card that rewards you for travel purchases. If you fly Frontier often, you may also consider adding the Frontier Airlines World Mastercard^® to your wallet, as it earns bonus miles on Frontier flights and on daily spending.

Hot Tip:

The price you see is just the base fee — it doesn’t include ancillary purchases like seat selection, baggage, or meals. As a budget airline, Frontier keeps costs low by passing along optional services to customers.

Final Thoughts
