The distance means nothing graham, TIME is the factor. everybody's life is a matter of time nowadays as you probably will agree.
Like you say GLA is 100+ miles away. So can I throw another argument in here:
How far is LHR from LGW from LTN from STN from LCY ???? Im sure the people who fly out of LGW would be pleased to know that because LTN is only 75 miles away that all charter flights will now operate from there !!!!!!
