The money is going to regional fields, not the hubs
Over the most recent five years, roughly $28.4 billion in federal Airport Improvement Program grants flowed to airports nationwide. Of that total, about $289 million went specifically to hangar, apron, and related general aviation projects across 337 airports.
The pattern is instructive. The largest hangar investments are not at the major airline hubs, which spend their federal dollars on runways and terminals, but at regional and small general aviation fields. That is precisely the market where new hangar capacity translates most directly into leasehold value. The airports below received the most hangar-directed federal funding in the current window.
