I've just realised, if the BA Secret Police read this I will have tipped them off. They will double the patrols, let the dogs out of the kennel, reinforce the barbed-wire. I'm doomed to failure.
Oh well, I'll have to resort top plan B. Enter the Club/Executive Lounge, walk down the connecting corridor where the toilets are and walk in the Concorde/First lounge as if we have just been to 'freshen-up'.
I'm OK to divuldge this trick, as the BA Secret Police only read the first paragraph of each posting before getting bored!
I suppose I could just ask them for access - but that ruins the fun!!
MERRY FLYER

PS: My next posting may be from the BA Boot-Camp!
