North American airports bet on cargo

North America’s major cargo hubs are running out of room, with Memphis, Louisville, Cincinnati and other gateways operating at or near capacity. That is creating an opening for secondary airports to attract freight by offering uncongested operations and additional infrastructure. Greenville-Spartanburg (GSP) is building around its manufacturing base, with BMW, Michelin, Volvo and hundreds of suppliers nearby. A new dedicated cargo area will separate freight from passenger operations, improve airside access and provide the ground infrastructure needed for regular freighter services, while GSP also positions itself as a link between Canada and Latin America. Harrisburg is pursuing the same opportunity, with a planned 105,000 sq ft cargo facility targeting freight that currently moves through Philadelphia and Baltimore. The broader case for secondary airports is strengthened by congestion at primary hubs and the growth of cost-sensitive e-commerce, with lower fees, uncongested operations and strong regional catchments giving airports such as GSP and Harrisburg a realistic opportunity to capture incremental freighter traffic.North America’s major cargo hubs are running out of room, with Memphis, Louisville, Cincinnati and other gateways operating at or near capacity. That is creating an opening for secondary airports to attract freight by offering uncongested operations and additional infrastructure. The big cargo hubs in North America are full. Not metaphorically. Physically, operationally, structurally full. Memphis, Louisville, Cincinnati, and the major gateway airports have been running at or near capacity for years, and the gap between freight demand and available infrastructure at those facilities is not closing anytime soon. So, cargo is starting to look elsewhere. And a handful of secondary airports have decided they want to be where it lands. Greenville-Spartanburg International Airport (GSP) in South Carolina is the most interesting example right now. The airport sits in the middle of one of the densest automotive manufacturing corridors in the United States, with BMW, Michelin, Volvo, and hundreds of tier-one and tier-two suppliers within trucking distance. It already handles automotive parts regularly. But GSP wants more than that. It is positioning itself as a flexible, uncongested bridge for freighter traffic between Canada and Latin America, and it is building the infrastructure to back that pitch up. A new dedicated cargo area development is under way at the airport, designed to separate freight operations from the passenger terminal, improve airside access, and give freighter operators the ground support infrastructure they need for scheduled operations rather than just occasional charters. Harrisburg Joins the Push GSP is not alone. Harrisburg International Airport in Pennsylvania has plans for a new 105,000 sq ft cargo facility, a development that puts it squarely in competition for Mid-Atlantic freight that currently defaults to Philadelphia or Baltimore. A facility that size, at an airport with lower fees and no slot constraints, is a serious proposition for smaller freighter operators and e-commerce fulfilment networks that need reliability without the complexity of a primary gateway. The Argument These Airports Are Making Secondary airports have been making versions of this argument for decades, and most of the time the freight stays at the big hubs anyway. So, what is different now? A few things. Congestion at major facilities has reached the point where it is no longer just an inconvenience. It is affecting service reliability in ways that cost airlines and forwarders real money. The secondary airport model already works in Europe, where Frankfurt-Hahn, Liege, and Ostend have captured significant freighter traffic that outgrew the primary hubs. And e-commerce volumes, which are less route-sensitive than express freight but highly cost-sensitive, are exactly the cargo type that secondary airports can serve competitively. GSP and Harrisburg are not going to replace Memphis. But they do not need to. They need to capture a slice of the market where their uncongested operations, lower costs, and regional manufacturing connections give them a genuine edge. The investment they are making now suggests they believe that slice is large enough to be worth chasing.
