In connection with the operation of an airport or airport facility owned or controlled by an authority, the authority may enter into contracts, leases, and other arrangements for terms not to exceed thirty years with any persons:
In each case the authority may establish the terms and conditions and fix the charges, rentals, or fees for the privileges or services, which shall be reasonable and uniform for the same class or privilege or service and shall be established with due regard to the property and improvements used and the expenses of operation to the authority. However, in no case may the public be deprived of its rightful, equal, and uniform use of the airport, airport facility, or portion or facility thereof.
