It is my understanding that the CAA is establishing a list of people who have legitimate need to access the flightdeck. ATCO's should certainly be on it. It is not the airlines who are preventing you from taking j/s rides, it's now the law. I can't even ride on the jumpseat unless I am on duty. Hopefully the CAA (or more correctly the DOT) will see the sense of allowing famil. trips to take place, don't hold your breath though.
