Nonstop flights from Tulsa to Denver are back, with ultra-low prices. Here's the catch.

Frontier Airlines will return to Tulsa International Airport this fall, launching new nonstop service to Denver beginning Oct. 12, the airline announced Tuesday.

The ultra-low fare carrier said it will offer the route twice weekly and is celebrating the return with promotional fares as low as $39.

The airline last served Tulsa in March 2022.

Stephanie Chester, director of marketing and customer engagement at Tulsa International Airport, said the return of Frontier adds value for local travelers. “As our airport continues to grow, Frontier’s return helps us deliver on our promise of accessible and affordable travel options for all,” the statement said.

According to the airline, the Denver flights are part of a broader upgrade to its customer offerings. Frontier has rolled out new features as part of what it’s calling “The New Frontier,” including UpFront Plus seating with extra space and a guaranteed empty middle seat, and upcoming First-Class seating set to debut later this year.

Frontier’s frequent flyer program, FRONTIER Miles, also offers perks like unlimited companion travel, priority boarding, and family mile pooling, with elite status available starting at 10,000 miles.

Promotional fares must be purchased by July 28 and are valid for select travel dates from Oct. 7 through Dec. 18, excluding blackout dates around Thanksgiving. Travelers can find full fare details and schedules at www.flyfrontier.com.
