Here in Europe, some aircrew have a habbit of introducing themselfs, and showing ID, to the SCA, upon bording.
I think it's a nice habbit, ( incase, that you have to pay for a coffe, it's usaully free
It's also always nice for them to know there is a ABP, incase the s*** hits the fan, they can use you....
They usally say, that you can stick your head in and say hello to the cockpit, if the crew seams nice, you can ask, or sometimes they just say, " wanna ride up here"' ?
But, as said it is from airline to airline....
Good luck.
