If this thread has already been done to death - I'm sorry but I searched back as far as I could and couldn't find one.
No doubt you FF Business Execs. out there bump into "Personalities" all the time but for us retired FF's , who have now to pay for our own Premium tickets as our miles have run out, it makes the pain of paying much easier.
My list is very short:-
Roger Moore (007) in Royal Orchid 1st Bangkok
Lord Dennis Healey (retired British Foreign Secretary) Nice Cote D`Azure lounge.
Douglas Hurd (another retired British Foreign Secretary) LHR4 Concorde lounge.
AND
Rowan Atkinson (actor) LHR3 London lounge [on his way to Mauritius]
We giggled like school kids when he left the lounge as , no doubt,"Mr.Bean" would have been shown on that flight!

And yours..............
