Good look with that at the likes of LHR, STN, LGW. i have turned up with a full crew in uniform with a UK airport ID, but one not issued by the above and have only being allowed airside after production of a GEN DEC
There is no way these days you'll be allowed airside through the C channel by saying it's ok GUV I'm on mi way home
If this is Ryanair we are talking about, what happens at say STN when you've flown in from BUD and you are heading for DUB? are you in uniform? do you go to the FR crew room and then walk out to the aircraft
