I think the easy answer is no. Certainly there has been some attempt by the federal government to fulfill its mandate in giving us some capital funding, but the large majority of airports, as you mentioned, in not been able to even participate because the funds simply aren't there to match the contribution agreements.
There's been nothing in the way of operational support since the late 1990s. These airports were transferred strictly to municipalities and local community governments, and the load is being borne by them.
