Delta is making a surprising move by ending its Austin-Harlingen route just five months after launching it. The airline, which has been expanding its presence in Austin, will stop operating this service on June 7. Instead, it will reallocate the aircraft to its Austin-Midland/Odessa route starting June 8.

Delta introduced daily flights between Austin–Bergstrom International Airport and Valley International Airport in October. However, stiff competition from Southwest Airlines, which dominates the route, may have influenced the airline’s decision. Data shows that Southwest offers significantly more seats on this route compared to Delta. As a result, Delta has decided to shift its focus to more profitable destinations.

Despite dropping this route, Delta continues to expand in Austin. The airline recently announced a new seasonal service to Cancun, Mexico, set to begin in December 2025. This marks Delta’s first international route from Austin, and the flights will operate until mid-April 2026. Additionally, Delta has been adding domestic routes, including a connection between Austin and New Orleans, which launched in February as part of its Mardi Gras event package.

Delta ranks as the third-largest airline in Austin, following Southwest and American Airlines. In 2024 alone, the carrier transported 3.3 million passengers through Austin–Bergstrom International Airport. While the Austin-Harlingen service is ending, Delta remains committed to strengthening its network from the city.

Looking ahead, the airline is gearing up for a busy summer. Delta plans to launch 20 new domestic routes and expand international services. The carrier will also introduce a new seasonal service between New York LaGuardia and Panama City, Florida. Additionally, it will restart or add international flights connecting major U.S. hubs to destinations like Dublin, Barcelona, and Milan.

Delta consistently evaluates its network to ensure efficient operations. The airline adapts to changing market conditions and shifts its resources to routes with higher demand. While some flights get discontinued, Delta remains focused on expanding its global footprint.
