And therein is the 'interesting' bit. Figures from bidbook show about 150ish blokes to go within the next five years (working on 60 here!). If all these blokes are on the 744 it could well create residual slots for 5-700+ training programs- including the 150 crew to replace them.
Any 'expansion' (extra aeroplanes) the airline does on top of what we have now (and that includes AO) adds another 14 direct entry pilots to the scene and will create 7 new commands and 14 new F/O training slots. Interesting times ahead.
