As I see it, DEFO is planned on the Airbus & jumbo (warning:freighter only flying!!)
That means that the 777 FOs will continue to be all be low or zero hour cadets.
Smart move Anna & Dom, clearly experience has become an issue (FOPS mangement's fault), so you urgently need experienced pilots to join. Then you decide to leave the ultra-low experience guys who desperately need sectors on the fleet where they'll get 1 sector a month, and put the high hour pilots on the fleets where they're likely to average 4-6 PF sectors a week.
Brilliant!!!
