Training and sim time is the cost of doing business at an airline. Do you think Lufthansa, Air France, United, etc upgrade people out of seniority from the right seat to the left seat on the 777/747 in order to save money and sim time? If they can run an airline properly then so can EY. If EY mgt really cared about training costs then they wouldn't be spending hundreds of millions of dirhams on over 150+ cadets, many of whom are expats and contribute nothing to the emiratization process. What does each cadet cost from start to finish? I would guess it's at least a million AED.
