Are you sure about your numbers Walnut? 20 new LH routes not only seems much higher than BA are estimating (only 20% of bmis original 56 slots were considered suitable for longhaul expansion), but they'd be literally years away and dependent on a favourable economic climate. Also you may require 10 crews for a long haul airframe but you've already got 5+ crews for the existing shorthaul airframe. Talk of huge expansion in pilot numbers is premature and they may never materialise.
