Frontier Airlines announced four new nonstop routes launching in late 2026, marking the latest expansion for the ultra-low-cost carrier as it capitalizes on the exit of competitor Spirit Airlines and strengthens its presence across the United States and Caribbean. The routes, announced July 14, will connect Denver, Detroit, Fort Lauderdale, Houston, Kansas City, Los Angeles, Orlando, and San Juan, with introductory fares starting at $69.
The new service begins November 20 with three routes: Denver to Fort Lauderdale, Detroit to Los Angeles, and Kansas City to Orlando, all operating on daily or near-daily schedules. A fourth route, Houston to San Juan, Puerto Rico, launches December 17 with daily service. Josh Flyr, vice president of network and operations design at Frontier, said the expansion reflects the airline’s commitment to affordable travel. “We are pleased to announce these new routes which will connect many popular destinations, including Houston, Denver, Orlando, Fort Lauderdale, San Juan, and more,” Flyr said in the announcement.
Frontier’s expansion comes as the airline aggressively fills capacity left vacant by Spirit Airlines’ May 2026 shutdown. CEO James Dempsey told investors that Frontier overlapped with Spirit on more than 100 routes—more than any other U.S. airline—positioning it uniquely to absorb demand. In May alone, Frontier added 3 million seats to its scheduled flying between June and September, according to analysis cited in media reports. The airline has increased capacity by 23 percent compared to the prior year, making it one of the fastest-growing carriers in the market.
The new routes reflect Frontier’s broader strategy to dominate budget travel in major metropolitan areas. The airline has committed to being the number-one low-fare carrier in the top 20 U.S. metros, a goal supported by fleet expansion and product upgrades. Beyond route growth, Frontier is introducing First Class seating in 2026, alongside existing improvements like UpFront Plus seating with extra legroom and enhanced loyalty benefits through its Frontier Miles program. These investments position the airline to compete across price and service tiers.
Frontier’s network additions are part of a larger reshuffling in the U.S. aviation market. Following Spirit’s collapse, airlines including JetBlue have also expanded into former Spirit markets. However, Frontier’s overlap with Spirit’s network gave it the greatest opportunity to scale quickly. The company expects revenue gains from the shift, with management projecting a 3 to 5 percent revenue uplift from absorbing former Spirit customers. By late 2026, airlines had replaced approximately 60 percent of Spirit’s former capacity, with Frontier leading that recovery.
Promotional fares for the new routes start at $69 one-way for Kansas City-Orlando service and $99 for other routes, valid for travel through January 4, 2027, with a 21-day advance purchase requirement. Tickets must be purchased by July 20, 2026, though blackout dates apply around major holidays.
