Following up on Will's comment regarding pics when parked at the gate..I can tell you that the first thing on our minds after shutting down the airplane is to get off the thing ASAP and beat "the masses" thru Immigration/customs then getting our spot on the bus before 16 F/A's arrive
That said, if folks are looking for pictures then the "junior man" (seniority wise) is assigned the task while the rest of us head out !!!
I can also tell you that comapny policy is no cockpit access pre-flight or during flight, No pic's of crew members, no pics of specific items, even we crew members are not allowed cameras during those same time periods.
Sam is in a good position being an accredited photog with publications in print. Airlines always go out of their way to accomodate folks in his position as long as the right ID's are presented.
