As major airlines assess the future of short-haul domestic routes, the question arises: Which US “Big Three” airline— 
American Airlines
, 
Delta Air Lines
, or 
United Airlines
—plans to operate the most sub-100-mile flights in November 2024?
Based on available data for November 2024 from Cirium, an aviation analytics company, American Airlines is projected to lead in the number of sub-100-mile flights, planning 2,683 flights with 177,738 seats and 14,984,834 available seat miles (ASMs). United Airlines, a close competitor, plans a comparable number of flights (2,696) but with fewer seats (167,610) and 13,137,116 ASMs. Delta Air Lines, in contrast, is taking a much more conservative approach, planning only 968 flights with 70,476 seats and a total ASM count of 6,101,846.

As the largest US airline by fleet size and destinations served, American Airlines leads the “Big Three” in sub-100-mile domestic flights. American’s extensive network allows it to connect smaller regional airports to its primary hubs, enhancing its reach and connecting passengers to a broad range of destinations. A major contributor to American’s dominance on short-haul routes is its hub in Charlotte Douglas International Airport
, as the airline announced 133 new jobs in the city.
