CREW ROOM MAILBOXES. The Company undertakes to provide and properly maintain a Flight Attendants' Crew Room at all crew bases. A Flight Attendant Mail Box will be provided for each Flight Attendant at the Flight Attendant's home base. There will be no expectation that Flight Attendants carry Company mail and/or aircraft supplies from base to base in the course of their duties, except for supplies required to perform their duties (i.e. manuals and surveys).
