The FAA's count is the general-aviation aircraft kept on the field (singles, twins, business jets, helicopters) from its Terminal Area Forecast, the latest year with an actual count; airline fleets are never counted as based anywhere, so a big airline airport shows a small number. The register section below shows how many aircraft are registered to owners in town, a different measure again.

27,307passengers boarded flights here in the FAA's fiscal year 2024

Takeoffs and landings a year about 25,464, the FAA's fiscal year 2024 (October 2023 to September 2024)
