How many Commercial Service Airports are there in the US?

• A. Just over 5,000
• B. About 2,500
• C. Around 8,000
• D. Around 12,000

Answer: (A)

Understanding how many airports are designated as Commercial Service Airports shows the extent of the network that offers scheduled passenger service. There are just over 5,000 airports in the United States that have commercial service, meaning they host scheduled airline flights and are tracked in the FAA/NPIAS system. This category includes both primary and nonprimary commercial-service airports, reflecting a broad spread of destinations—from large hubs to smaller regional facilities.

The other numbers don’t fit because they either underestimate the breadth of airports that offer scheduled service (2,500) or exceed the scale of the U.S. airport system (8,000 or 12,000). In short, just over five thousand captures the official count of airports with active commercial service.
