Definition
Publicly owned airports that receive scheduled passenger service from airlines and board at least 2,500 paying passengers per year. They are classified by the FAA into two groups: primary airports (more than 10,000 passenger boardings annually) and nonprimary commercial service airports (between 2,500 and 10,000 boardings annually).
Plain English
Public airports that handle airline flights carrying paying passengers, with enough yearly traffic to meet a minimum threshold set by the FAA.
Context Anchor
Seen in airport category discussions, especially when learning how the Federal Aviation Administration groups airports by the type and amount of passenger service they provide.
Derivation
Commercial comes from commerce, meaning trade or business. In this aviation use, it points to airline passenger service offered to the public, not just any business activity at an airport.
Why Pilots Care
Pilots can expect longer runways, instrument approaches, control towers, and more ground services at these airports.
Intuition Check
Do not read “commercial” here as “any airport where money is involved.” In this FAA category, it means a publicly owned airport with scheduled passenger airline service and at least 2,500 passenger boardings per year.
Example Sentence 1
Because the destination was a commercial service airport, the student pilot reviewed airline traffic patterns and tower procedures before the cross-country flight.
Example Sentence 2
At the commercial service airport the pilot used the passenger terminal to file a flight plan before departure.
