What type of entities might contractors include when working at an airport?

Contractors working at an airport can be any business that holds an appropriate contract, making the second choice the most accurate. Airports often require a range of services, which can include ground handling, maintenance, cleaning, security, and more. As a result, a variety of entities can operate at an airport, provided they meet the legal and regulatory requirements outlined in their contracts.

These can include small local businesses, large national firms, and even multi-national corporations, depending on the nature of the services provided. The flexibility of including any business with an appropriate contract highlights the diverse operational needs of an airport and the complexity of the contracting process involved. While certain entities like governmental organizations or international corporations might be present, they are not the sole types of contractors allowed to work at an airport. Thus, the correct answer encompasses the broad range of possibilities for contractor engagement.
