Nite_Flite,
I've just re-read my previous post and it does appear somewhat abrupt; it wasn't intended and I apologise. (Perhaps one too many early starts in a row!)
ETOPS has explained the situation with regard to CityFlyer and Brymon.
Time to command is a difficult question as the goalposts are constantly moving. At the moment it is reckoned to be about 6 years to a command in shorthaul but that figure could alter massively. It is dependent on so many variables. Obvious factors are the state of the worldwide economy and the state of profitability within BA itself. My personal advice would be never to make any plans whatsoever on attaining a command within a set time period; if it happens then great but if it doesn't then you won't be overly disappointed. Not much help I know but it is the best I can offer.
I wish you well if BA is the choice for you.
Regards
Exeng
