Wait until the company petitions the FAA to issue all ramp personnel FAA Certificates (Just like Flight Attendants have now) and we'll be right back to Pre 911 style riders... just saying.
I don't know of any 121 carrier that allows flight attendants to use cockpit jumpseats. And as much as a crewmember that they are, I'm sure the FAA won't ever see them in the same light as mechanics.
