Although faring significantly better than rival Spirit Airlines and its two bankruptcies, Denver-based Frontier Airlines is certainly not immune from market forces rocking the low-cost airline model.

After breaking through a string of unprofitable quarters with fourth-quarter income of $53 million earlier this month, Frontier just cut its annual growth expectations by 10% and published a plan to return 24 of its Airbus A320 aircraft to lender AerCap as part of its efforts to cut costs.

With fewer planes, Frontier will also need to significantly rework its flight network.

This week, aviation industry watchdogs including Simple Flying reported that the carrier will cut nine flights out of John F. Kennedy International Airport (JFK) in New York by spring 2026.

Frontier will cut flights to Miami, Las Vegas, and Chicago from JFK by April 2026

Although Frontier’s reduction of flights from JFK does not represent an exit of the New York market (Frontier will continue to run an extensive network into both LaGuardia and Newark Liberty airports), it does cut the two longest routes run by Frontier: JFK to LAX and Harry Reid International Airport (LAS) in Las Vegas.

The route to LAX, representing the second-longest flight in Frontier’s network, was quietly cut in January. And the 1,953-nautical-mile route to Las Vegas was set to return for the season on April 14 but is now being axed, alongside Frontier’s flights to Chicago O’Hare, Dallas-Fort Worth, Denver, Miami, Orlando, Tampa, and Luis Muñoz Marín International Airport in San José.

All of these flights are either already off and not returning for the season or will be phased out by April 2026. The only remaining Frontier flight from JFK will run daily to Hartsfield-Jackson Atlanta International Airport (ATL) for now, as it is unclear how long Frontier will maintain a presence at the airport with a single flight.

As the primary commercial airport serving NYC, JFK is an expensive airport to fly into, both in terms of fees and airport slots for which more airlines compete.

Frontier Airlines is almost entirely axing its flight network out of JFK.

“We periodically review routes based on market demand”: Frontier Airlines

Frontier Airlines At the start of the year, Frontier was on track to move from JFK’s Terminal 7 to the newer Terminal 6. While the airline has offered no new information on this plan, the transition will likely be derailed, given the carrier’s lowered need and presence at the airport.

“We periodically review and update routes based on market demand, seasonality, costs associated with operating from a particular airport, and other factors,” Frontier said of the cuts in a Feb. 23 media statement.

MoreTravel News: As part of the policy stated on Frontier’s website, customers with flights that end up canceled by the airline are entitled to a refund “to the original form of payment,” should they not wish to accept the proposed rebooking option.

Frontier will contact customers, offering options for those who had already booked flights on the canceled JFK routes beyond April.
