Well that would be me and about half the flight crew in BA, along with a signifcant percentage of cabin crew who drive even further (Nottingham, Devon, Cornwall!). BAs guidelines are that you should live within 2 hours drive of work. I think CAP 371 has limits on how far you can travel on company time before its factored into your duty but I'm not aware it dictates how far/long you drive to work. Might be wrong though. Anyway, its taken me two hours to get to Central London from LHR!
