In a landmark shift in the global express air cargo market, UPS has overtaken FedEx to operate the world’s busiest express cargo hub. The carrier’s Worldport facility at Louisville Muhammad Ali International Airport (SDF) now surpasses FedEx’s Memphis hub (MEM) in both daily flight operations and tonnage capacity, according to the latest Global Cargo Hub Review from the Chaddick Institute for Metropolitan Development at DePaul University.
“In every scenario for flight activity and available tonnage capacity we considered, Louisville is now larger than Memphis,” noted Joseph Schwieterman, lead author of the report. “People often immediately think of FedEx’s Memphis hub when discussing express air cargo, but UPS’s Louisville hub has firmly elbowed its way to the top.”
Strategic Investment and Operational Flexibility Drive Growth
Louisville’s rise reflects UPS’s strategic investment in infrastructure, capacity expansion, and adaptive operations to meet changing freight demand. The Worldport facility now handles an average of 202.3 peak-day flights, outpacing Memphis’s 164.7 departures by nearly 40 flights, even after accounting for weather-related disruptions.
FedEx’s Memphis hub has reduced daytime departures by 66 flights (60.3%) since September 2022 as part of its “FedEx 2.0” initiative, which aims to integrate ground and air operations for improved payload utilisation and operational efficiency. By contrast, UPS has maintained peak-day schedules and slightly reduced afternoon flights, ensuring consistent throughput.
Beyond peak periods, Louisville also surpasses Memphis in off-peak and cumulative weekly flight activity, consolidating its position as the busiest hub globally by total operations.
Tonnage and Volume Leadership
In addition to flight activity, Louisville leads in tonnage and volume. On peak days, UPS SDF processes 33.4% more tonnage and 33% more volume than FedEx MEM. Other major hubs ranking behind include FedEx Liege (Belgium), DHL Leipzig (Germany), and SF Airlines’ Ezhou hub (China), each operating more than 45 flights per day, while FedEx’s Paris Charles de Gaulle hub follows closely.
Despite Louisville’s dominance, Memphis retains unmatched network reach, serving 116 nonstop destinations on a typical peak day versus 98 for Louisville. Memphis also maintains the highest number of early-morning departures (pre-6 a.m.), underscoring its continued strategic influence in express logistics.
Global Hub Expansion
While U.S. hubs continue to dominate the sector, the report notes rapid growth in China and Europe. SF Airlines and China Postal Service are expanding hub operations at Ezhou Huahu International Airport and other facilities in Beijing, Shenzhen, Hangzhou, and Nanjing, mirroring Western hub models. Japan’s Kansai International Airport hosts key operations from SF Airlines and Shandong Airlines.
Nonetheless, the world’s largest express hubs remain heavily concentrated in the northern hemisphere, operated by UPS, FedEx, DHL, SF Airlines, and their strategic partners. Comparable-scale hubs have yet to emerge in Africa, India, South America, or other regions.
Evolving Market Dynamics
Louisville’s ascendance illustrates the evolving dynamics of the express air cargo market: strategic infrastructure, responsiveness to shifting freight patterns, and operational agility are reshaping hub hierarchies. As global e-commerce and air freight demand continue to grow, UPS Worldport at Louisville sets a new benchmark for efficiency, capacity, and peak-day throughput.
