I recently saw a headline that uniforms are now being required to use the KCM checkpoint and how everyone is mad about it. I've always been kind of curious how security access works for pilots who are showing up for work vs those who are commuting vs those who are just traveling for fun. Obviously if you're working that day in full uniform you just stroll through this KCM area and its no big deal. I'd imagine this is the same for commuters, but what if you're just traveling for fun to Vegas for the weekend, any restrictions? To the layman I can't see how TSA guys would know what your purpose is, but wasn't sure if the SOP at the airline forbid it or how it worked. Would this render getting something like TSA-precheck pointless? Can you basically bring anything through, are bags checked? Similar to the above, do crew members have different access to the airport such as different parking areas to make it more convenient or back doors in a way to get to wear they need to be? Can a pilot just traveling for fun use these perks?
