NEW YORK— Delta Air Lines (DL) is cutting four domestic routes from its winter schedule, removing services from New York and Las Vegas before the end of 2026.
The changes will affect New York LaGuardia Airport (LGA), New York John F. Kennedy International Airport (JFK), Harry Reid International Airport (LAS), Tulsa International Airport (TUL), Milwaukee Mitchell International Airport (MKE), John Wayne Airport (SNA), and San Diego International Airport (SAN).
The latest schedule changes will see Delta end four regional routes between November and December.
The cuts come as the airline continues to adjust its domestic network, while weaker domestic traffic in Las Vegas and higher operating costs create additional pressure on shorter routes.
Delta Ends 4 Routes This Winter
Delta will first end its daily service between LaGuardia and Tulsa on November 6, 2026. The 1,235-mile route currently operates with a Bombardier CRJ900 and launched in November 2024, giving the service less than two years of operation before its scheduled termination.
Two days later, Delta will remove both of its Las Vegas routes to Southern California. The airline’s twice-daily service between Las Vegas and Orange County will end on November 8, alongside its once-daily Las Vegas-San Diego service.
Both California routes operate with Embraer E175 regional jets through Delta Connection. Delta restored the Las Vegas-Orange County route in early 2025, while its San Diego operation had already been reduced from two daily flights to one earlier this year.
The final change will come on December 18, when Delta ends its daily service between JFK and Milwaukee.
The 747-mile route is operated with a Bombardier CRJ900 and has become a particularly notable market because Delta currently provides the only nonstop service between the two cities.
New York Network Shifts This Winter
The four cancellations follow additional changes to Delta’s New York network. In July, the airline confirmed that JFK services to Memphis, St. Louis, and Houston would not return after being suspended in June.
The strategy increasingly points toward a division of roles between Delta’s two major New York airports.
Shorter domestic markets within LaGuardia’s 1,500-mile perimeter can be concentrated at LGA, while JFK can provide more capacity for international and longer-distance operations.
The adjustment could also help Delta make more efficient use of limited airport slots.
Rather than maintaining overlapping short-haul operations at both airports, the airline can focus its New York network around the strengths of each hub.
Las Vegas Demand Weakens Amid Traffic Decline
Delta’s Las Vegas cuts also come as Harry Reid International experiences softer passenger traffic. The airport handled 4.41 million passengers in July 2026, down 7.6% from the same month a year earlier, while domestic traffic fell 8.7%.
Through the first seven months of 2026, Harry Reid handled about 30.2 million passengers, representing a decline of roughly 6.9% year over year. International traffic was stronger, but it was not enough to offset the decline in domestic travelers, Simple Flying reported.
Cost pressures are another factor affecting airline network decisions.
Delta reported adjusted second-quarter fuel expense of $4.41 billion, up 77% year over year, while its adjusted average fuel price reached $3.93 per gallon.
For passengers, Delta’s four route cancellations will reduce nonstop options during the winter season.
However, alternative airlines continue to serve several of the affected city pairs, while Delta will retain service to some of the affected airports through other markets.
