Flight Deck - about 90% ok IAG will just get rid of the dead wood,poor sickness records
Cabin Crew- see flight deck
Ground Staff- tricky one i suppose some at LHR will be offered jobs , out stations without BA bases prob ok for while to see if route continues,those with bases probably at risk, those at the hall prob 80% will be made redundant poss 20% offered positions with IAG
cant see it going any other way
as for the timescale i suspect bmi will cease to exist after summer 2012
