What the hub types mean
The FAA groups commercial service airports by their share of national passenger boardings: large hubs handle at least 1% of U.S. enplanements, medium hubs 0.25% to 1%, and small hubs 0.05% to 0.25%. Below them are nonhub primary airports and nonprimary commercial service airports.
Selling to airports
Airports are run by cities, counties, states and independent airport authorities, so they buy like public agencies — through published solicitations, board or council approvals and capital plans. Many projects are paid for in part by the FAA's Airport Improvement Program and passenger facility charges.
- Know who owns the problem. Airport directors, operations and maintenance leaders, IT and security staff, and aircraft rescue and firefighting (ARFF) units usually shape requirements.
- Watch the capital plan. Terminal, airfield and technology projects show up in airport capital improvement plans and board agendas years before they're bid.
- Don't skip the smaller airports. Small hubs and nonhub airports have smaller teams and often get less vendor attention.
For KOVA, KSG reached airport directors, operations staff and ARFF units at large and regional airports, adding 164 opportunities and $5 million in revenue. See our special districts and airports page.
About this data
The figures are the FAA's final calendar year 2025 enplanement counts from its Air Carrier Activity Information System, published September 24, 2026. Enplanements count passengers boarding aircraft, so each round trip counts once at each end. Percent change is calculated from the FAA's 2025 and 2024 figures.
