Where Your Packages Sleep: Inside Air Cargo’s Hidden Hubs

Most of us fly through JFK, Heathrow, or Atlanta. But the world’s busiest cargo airports are places you’ve probably never connected through: Memphis, Anchorage, Louisville, Liège. This episode maps the parallel geography of global air freight — the mega-nodes where FedEx, UPS, and DHL sort millions of packages a night, the fuel stops that keep Asia-to-North America routes viable, and the freight-only airports emerging because passenger hubs are too congested and expensive for cargo. We explain why cargo hubs cluster around factories and geographic chokepoints — not tourist destinations — and how geopolitical crises can reshape the network in days.
