What concept must airport operators remember regarding their operations?

Airport operators must remember that they operate as a public entity that is also a business entity. This dual nature is critical in understanding their responsibilities and the framework within which they function. As public entities, airports serve the broader community, providing transportation infrastructure that benefits society as a whole. This entails adhering to regulations, policies, and standards that ensure safety, accessibility, and efficient operation.

Simultaneously, as business entities, airports must ensure financial sustainability, manage resources effectively, and often compete for airline services, passengers, and cargo. Balancing these aspects is essential for successful management and operation.

The other choices do not encapsulate the core operational philosophy necessary for airport operators, as they either limit the scope of services or misrepresent the regulatory environment in which these airports function.
