For those who complain about nobody being able to see what
goes on up front in an airliner, I believe there is plenty of
videos on the market ("flying the big jets etc") that would
show what it's like.
Having been on Europen flights where the cockpit door
was a revolving door for all the kids to come up and take a look,
I think I prefer the US way where only a qualified individual is allowed to ride up front.
As far as taking away the right of a company pilot traveling
off duty in the cockpit I strongly disagree.
At the moment my airline can only take jumpseat pilots who can be verified in a database , which leaves out most other airlines, but at least I can offer a free seat in the back (if available)to
any Part 121 Airline pilot.
