"ALPA has been notified by the Transportation Security Administration (TSA) that effective November 1, it amended the Aircraft Operator Standard Security Program (AOSSP) to allow sterile-area access for crewmembers consistent with regulations that were in effect before July 2006. As a result, commuting pilots will no longer be required to obtain a boarding pass before entering the security checkpoint at airports that their airlines do not serve."

Hope this helps
