Certainly, the days when pax could walk on board and ask for the j/s for landing (or more) are long gone, on any airline, but it is heartening to know that the whole world hasn't gone into TSA/FAA/CAA-land.
Quite apart from an appreciation of the fact that there are many aspiring pilots who could benefit from such access, there is also the aspect of facilitating aviation articles and videos, which are very popular and could serve very effectively as a training aid as well as a keepsake for enthusiasts.
For my own part, I used to write "from the cockpit" articles for a US magazine and that's now almost impossible to organise - but I will be trying other other carriers now!
