Airline information on-line on the Internet FAQ

Other changes include: some airports have stopped curb-side baggage check,
anything vaguely resembling a knife may or may not be confiscated, you're
often only allowed one carry-on plus a purse, briefcase, diaper bag or the
like, non-passengers aren't allowed past security without a gate pass from an
airline, all passengers must have a boarding pass (not just a copy of the |
itinerary) at most airports to get past security, some parking areas close to |
terminals are closed.,

A listing of US Airports served by US Airways that absolutely require boarding passes to clear security
checkpoints is at http://www.usairways.com/customers/t...ints/index.htm

Other airports not listed (but served by US Airways) do not require boarding passes to secure security.

I apoligize for the US Airways aspect of this information, but it is the only list of these airports
that I've seen so far.
