On October 8, the carrier inaugurated flights from New York JFK to Chicago O’Hare (mainly four weekly), JFK to Denver (mainly three weekly), and Dallas/Fort Worth to El Paso (mainly three weekly). These are all new markets for Frontier. On the JFK-O’Hare route, Frontier joins American, Delta, and JetBlue. It is now the first time in two decades that four airlines serve this airport pair simultaneously. For JFK-Denver, it faces competition from JetBlue and Delta; this market last had three carriers before American exited in 2018. Dallas/Fort Worth-El Paso has not seen two operators since Delta left in 2005.
On October 9 and 10, eight additional routes were launched by Frontier as part of its strategy of offering low fares in markets already served by other airlines—often those with higher prices. Unlike Allegiant or Breeze—which usually enter unserved markets—Frontier focuses on competitive markets but offers less frequent service: often just two or three flights per week.
The Denver-Corpus Christi flight is unique among these launches because it faces no direct competition; U.S. Department of Transportation data indicates there were previously no regular flights on this route. In the year ending June 2025, an average of 56 local passengers traveled daily between these cities using connections—a number likely to grow with nonstop service now available.
Other new routes include Dallas/Fort Worth-Charleston (South Carolina), Dallas/Fort Worth-Tucson, Phoenix-Kansas City, Salt Lake City-Santa Ana (California), Atlanta-Omaha, Phoenix-San Antonio, and Phoenix-St Louis—with most facing established carriers such as American Airlines or Southwest Airlines.
For example, Atlanta-Omaha was previously served by Southwest until early 2025 when that carrier reduced operations at Hartsfield-Jackson Atlanta International Airport. According to U.S. DOT figures covering July 2024 through June 2025, about a quarter of the roughly 324 daily local passengers used Southwest before its withdrawal; Frontier aims to attract some of this demand with twice-weekly flights instead of daily service.
On October 11 and 12, Frontier will add Tampa-Kansas City (up to three times weekly) and Tampa-St Louis (up to twice weekly)—both previously served by the airline—and Denver-Tulsa (mainly twice weekly). In each case they will compete with Southwest or United Airlines where applicable.
As Frontier continues its expansion into both competitive and underserved markets with sub-daily frequencies aimed at price-sensitive travelers seeking lower fares despite fewer schedule options—industry observers will watch whether these strategies succeed against established carriers.
