Frontier Airlines adds 14 new routes across US as network shake-up bleeds into 2025

Frontier Airlines is plotting a big network shake-up that's set to take effect right before the peak 2025 summer travel season gets into full swing.

The Denver-based ultra-low-cost carrier will add more than a dozen new routes in May at airports across the country — including a new route to the northwest tip of Puerto Rico.

In all, Frontier's expansion is 14 new routes, all of which will launch in the days leading up to Memorial Day weekend — the annual unofficial start of summer travel.

Miami, Los Angeles, Dallas, Washington, DC, and others see biggest growth

The biggest winner in Tuesday's route drop: Dulles International Airport (IAD) near Washington, D.C., which will get three new nonstop destinations aboard the budget airline.

Frontier has been expanding at the D.C.-area airport in recent months after returning to Dulles for the first time in several years in late 2024. It also revealed plans to bolster its footprint at the airport just days ago.

Here's what the airline's Dulles route map will look like come May:

Frontier will also launch two routes apiece from Los Angeles International Airport (LAX), Dallas Fort Worth International Airport (DFW), Austin-Bergstrom International Airport (AUS) and Cleveland Hopkins International Airport (CLE), plus three from Miami International Airport (MIA).

Also getting a pair of routes: Frontier's home base at Denver International Airport (DEN).

All those airports are places where the carrier has added flights over the last year amid a larger network realignment.

Frontier's 14 new routes

Here's the full slate of Frontier's 14 new routes announced Tuesday:

Furthering its strategy in 2025

A majority of Frontier's 14 routes unveiled Tuesday are entirely new to the airline. However, it previously flew a handful of them within the last decade.

Frontier last served its short-haul Boise and Spokane routes from its Denver base in 2021.

And it flew AUS-PHL, IAD-MIA and LAX-ORD in the mid- to late 2010s.

Tuesday's network announcement is Frontier's biggest of 2025 after the carrier made vast changes to where — and when — it flies in 2024.

Last year, the carrier realigned its network to focus less heavily on competitive domestic vacation spots like Orlando, opting instead to try to lure travelers flying between big cities to visit friends and relatives.

Later in 2024, the carrier also reduced its midweek flying on days like Tuesday and Wednesday, when fewer leisure travelers are on the road. That schedule tweak remains in place for 2025, Frontier president James Dempsey said on the company's most recent earnings call earlier this month.

"We've spent the last 18 months trying to adjust our network to meet the demand patterns that exist in today's environment," Dempsey told analysts. "What we've done is really shape the week in a better way where we focus a lot of our flying on peak days, and it comes at the expense of off-peak days of the week."

Elite status deal sweetener

The carrier is also hoping to entice travelers to focus more on its Frontier Miles loyalty program, with a companion pass for high-level elite status members set to launch later this year and a shortcut to elite status between now and late April that should be more easily attainable for travelers who carry the Frontier Airlines World Mastercard®.
