that was done as a security measure after 911. befroe 911 no airline crew id said "crew" on it. after that terrible day. i think the tsa required all airlines to place the "crew" designator on all flight crew badges. so i think this has to be put on all flight crew i.d's.The East flight crew ID's also have "CREW" written on them in bold letters. I believe this has to do with access, as well.
When the last batch of East ID's were issued, the CREW designation was left off the flight crew ID's, requiring that all flight crew ID's had to be re-issued, at great expense.
To the management folks monitoring this forum, let's not make that expensive mistake again, okay?
