i believe about 60% of the cabin crew commute to and from heathrow.thats from UK airports and throughout europe and beyond.if longhaul crew had to fit shorthaul flying into their rosters,that would prove virtually impossible,if commuting some distance to work.considering the problems trying to park in the staff car park ,if commuting crews who now fly,opted to relocate near london and drive to work,another staff parking area would have to be provided,just think of the cost to BA of another huge car park ! if it could be secured near to T5,what a problem.also the loss of revenue from id90 commuters.all these proposals have problems attached.the current lack of facilities for staff driving to work is just one i can think of.
