Delta Cuts Four U.S. Routes From New York and Las Vegas
Delta Air Lines will end service on four domestic routes from New York and Las Vegas by December 2026, consolidating short-haul flying at LaGuardia and
Delta Air Lines is ending service on four domestic routes from New York and Las Vegas by the end of 2026. According to schedule updates reported by Ishrion Aviation, the cuts involve Delta Connection flights operated by regional jets.
The first route to be dropped is the 1,235-mile connection between New York's LaGuardia Airport (LGA) and Tulsa International Airport (TUL). Its final flight is scheduled for November 6. Delta currently operates this once-daily service with a Bombardier CRJ900. The route, which launched in November 2024, will have flown for less than two years.
On November 8, Delta will end two short routes from Las Vegas. Services to both Orange County's John Wayne Airport (SNA) and San Diego International Airport (SAN) will conclude. SkyWest Airlines operates these flights, each under 300 miles, using its Embraer E175 fleet. Delta had reinstated the Las Vegas-Orange County pairing in early 2025. The San Diego service had already been reduced from two daily flights to one earlier this year.
Finally, the carrier's daily 747-mile flight between New York John F. Kennedy International Airport (JFK) and Milwaukee Mitchell International Airport (MKE) will end on December 18. Delta has been the sole operator on this route since JetBlue ended its service in October 2025.
Route Details and Aircraft
All four routes are operated as Delta Connection services using smaller regional jets, with one or two flights per day. The following table summarizes the routes being cut:
| Route | Final Flight Date | Distance | Current Aircraft | Notes |
|---|---|---|---|---|
| New York LaGuardia (LGA), Tulsa (TUL) | November 6, 2026 | 1,235 miles | Bombardier CRJ900 | Launched November 2024. |
| Las Vegas (LAS), Orange County (SNA) | November 8, 2026 | Under 300 miles | Embraer E175 | Reinstated early 2025. |
| Las Vegas (LAS), San Diego (SAN) | November 8, 2026 | Under 300 miles | Embraer E175 | Previously reduced to one daily flight. |
| New York JFK (JFK), Milwaukee (MKE) | December 18, 2026 | 747 miles | Regional Jet | Delta became sole operator after Oct 2025. |
Consolidation at New York Airports
These cuts follow other recent reductions at New York JFK. Delta confirmed in July that flights from JFK to Memphis (MEM), St. Louis (STL), and Houston Intercontinental (IAH) would not return after being suspended in June. Those three routes had launched in September 2025, lasting less than a year.
With the airports for these discontinued routes-including Milwaukee and Tulsa-falling within LaGuardia's 1,500-mile perimeter, the cuts allow Delta to consolidate its short-haul services at LGA. This strategy frees up valuable slots at JFK, which Delta prefers to use for international and longer-distance flights. Travelers can still fly Delta to Houston, Memphis, Milwaukee, and St. Louis from LaGuardia, but Tulsa will lose its direct Delta connection to New York.
Factors Behind the Las Vegas Cuts
Data shows a decline in passenger traffic at Las Vegas's Harry Reid International Airport throughout 2026. The airport handled 4.4 million travelers in July, a 7.6% reduction compared to July 2025. While international traffic rose by 6%, a domestic traffic drop of 8.7% drove the overall decline. Across the first seven months of 2026, the airport handled 30.2 million passengers, a 6.9% decline from the same period in 2025.
Delta has been strategically reducing its short-haul operation from Las Vegas. It ended service to Sacramento and San Jose in January. The San Diego route faced stiff competition from both Southwest Airlines and Alaska Airlines, which offer substantially more flights. An ongoing fuel cost crunch has also been a significant factor in Delta's wider network decisions. The carrier's second-quarter fuel bill reached a record $4.4 billion, which is 77% higher than the previous year. Shorter domestic routes are often among the first cut during cost-saving moves, as they are typically among the least profitable.
