I agree that the fam flights for you guys can help in these situations but they are still available

. I have arranged two fam flights for ATC staff (both post 9/11) with my present company and my last and it was all easily arranged and all above board. With regards to my present and previous employer, both had a blurb in the ops manual saying that fam flights were allowed for ATC staff providing prior permission was sought through the normal channels. I am not sure what the rules are for every UK operator but I would hazard a guess that most of them would still welcome you with open arms!!
