Talk about seeing the silver lining....

If there is a dramatic reduction in commercial ticket sales, the Av. Trust
fund revenues will wither (similar to the post- 9/11 situation), since
commerical ticket taxes comprise the overwhelming bulk of trust fund
revenues.

In that case, the already considerable political pressure to impose user
fees will probably be unstoppable. And GA airports receiving annual
operating and capital subsidies will have to finance projects on their own
and will have to generate revenues sufficient to cover expenses without
federal handouts (as it should be, obviously).
