Memphis International Airport and the FedEx hub

Memphis International Airport is home to FedEx's global air hub (FedEx SuperHub) and has been described as the world's busiest cargo airport by tonnage. The constant night-time cargo flights and the city's association with FedEx are frequent targets of local jokes about working nights, package volume, and Memphis's 24-hour logistics identity. The airport's role in the local economy and nighttime activity is well documented in transportation and economic sources. Its status as a cargo hub is a verifiable fact tied to the airport's operations.
