Which code does this activity belong in?
The boundary between these codes separates specialized services performed on or for aircraft from the broader airport infrastructure operations. Code 488190 covers establishments providing maintenance, repair, testing, and security screening directly related to aircraft themselves. Code 48811 covers airport operations and support services, including hangar rentals, baggage handling, cargo handling, air traffic control, and other activities that facilitate airport functioning rather than serve individual aircraft.
