I know it is pretty common for government agencies and quasi-agencies to advertise, at least in my area. I see ads for the community colleges, state tourist agency, recreation programs, water service and, yes airport services, among many others. But that is my area. The real answer to your question lies in the agency or region that controls your airport. Some airports are special quasi-government agencies, some are independent, some are run by regional governments. It is the set of laws of that entity that would determine whether or not it is legal.

Thanks for your question, smac. Advertising done by or on behalf of the U.S. government and state governments are usually watched very closely by watchdog groups. Some advertisements, especially for the U.S. Postal Service or Armed Forces are regularly promoted in the media.
