Low-cost Denver-based Frontier Airlines has launched nonstop service from Dallas Fort Worth International Airport (DFW) to two new destinations in Central America.

According to a release, the carrier will offer the following new flights:

• Guatemala City, Guatemala (GUA) - weekly
• San Salvador, El Salvador (SAL) - 2x/week

With these new routes, Frontier will serve 40 destinations nonstop from DFW, exemplifying Frontier’s impressive network growth as it continues to add more affordable and convenient travel options across the U.S., Caribbean, and Latin America.

The frequency of the flights is a little confusing. Guatemala City is "weekly" which seems to imply "once a week." San Salvador is "2x/week" which seems to imply two flights a week. However, if you try to book a flight to either city, you get all sorts of options, including weekends and a few randomly spaced weekdays. And the flight availability extends only through January.

Frontier Airlines VP of network and operations design Josh Flyr says in a statement that "there’s a lot to be excited about" including their expanding network and their rolling out First Class in early 2026.

Other changes at Frontier include UpFront Plus seating, an upgraded seating option with extra leg and elbow room in the first two rows of the aircraft, with choice of a window or aisle seat with extra legroom and a guaranteed empty middle seat.

To celebrate, they'll offer a fare sale starting at $79. Tickets must be purchased by 10:59 pm Dallas time on December 30, 2025. Sale fares are valid for nonstop travel on select days of the week January 5-April 13, 2026. Blackout dates apply on March 9 and March 31, and from April 1-6. And a 14-day advance purchase is required.
