Not met this diverse bunch on flights per se but here goes:
Pete Waterman - Really nice guy, took time to talk to everyone and pose for photos
Daniel Bedingfield - Took time out after concert to meet and chat to fans (was with my sister hasten to add!).
Michael Greco (ex Eastenders) - very amiable and friendly
Felix Buxton (Basement Jaxx) - In my class at school. Top bloke.
Eddie "the Eagle" Edwards - met recently whilst he was studying law - great laugh
Yet to meet a bad one.
