CHICAGO- Delta Air Lines (DL) is reducing its U.S. network this winter, with five routes scheduled to end between November and December 2026. The changes affect seven cities and include services from New York, Las Vegas, Southern California, Oklahoma, and Wisconsin.
The network adjustment will particularly affect travelers using John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), and Harry Reid International Airport (LAS).
Delta said the Las Vegas reductions reflect weaker winter travel demand, while its wider network changes are part of an ongoing review of schedules against customer demand.
Delta Route Cuts Across Five Cities
Delta will discontinue five routes before the end of the year, with the first changes arriving in November. The affected services connect New York with Tulsa, Palm Springs, and Milwaukee, while two Las Vegas routes link the city with Southern California.
The schedule changes are:
- LAS–San Diego International Airport (SAN): November 8
- LAS–John Wayne Airport (SNA): November 8
- LGA–Tulsa International Airport (TUL): November 9
- JFK–Palm Springs International Airport (PSP): December 19
- JFK–Milwaukee Mitchell International Airport (MKE): December 19
The JFK–Palm Springs service is a Saturday-only operation, making its December withdrawal a targeted reduction rather than a daily route cancellation.
Delta will continue serving Milwaukee from LaGuardia, with four daily round-trip flights between LGA and MKE.
Delta has said it regularly evaluates its network to align capacity with customer demand. Passengers affected by the discontinued services will be contacted by the airline regarding changes to their travel plans.
Las Vegas Capacity Faces Winter Cuts
The most significant capacity reduction will occur at Harry Reid International Airport, where Delta plans to operate fewer flights this winter.
Cirium data indicates that Delta’s total departures from LAS will fall by roughly 7% compared with the same period last year.
The reduction comes as Las Vegas continues to experience softer tourism demand. The Las Vegas Convention and Visitors Authority reported that the destination welcomed approximately 38.5 million visitors in 2025, representing a 7.5% decline from 2024.
Airport traffic has also reflected the weaker market. Recent industry reporting indicates that passenger demand at Harry Reid has remained below previous-year levels, adding pressure on airlines to adjust capacity on selected routes.
January Vegas Service Returns Briefly
Despite the winter reductions, Delta is not completely leaving the affected Southern California markets. The airline plans to restore limited Las Vegas service from San Diego and Orange County in early January.
Those flights are expected to support demand surrounding the Consumer Electronics Show, one of Las Vegas’ largest annual business events.
Delta has previously placed significant emphasis on the event, including promotional activity connected with the Sphere.
The temporary January operation shows that Delta is adjusting capacity around periods of stronger demand rather than removing the Las Vegas markets permanently, The Points Guy reported.
The airline’s broader winter schedule, however, indicates a more cautious approach to leisure travel demand in the city.
Las Vegas hosted nearly 6 million convention attendees in 2025, helping offset some weakness in leisure visitation. Even so, overall visitor numbers, hotel occupancy, and airport traffic declined, creating a challenging environment for airlines operating capacity into the market.
