Hello,
Bullwinkle, Cant understand your logic, the A330s are utilised approx 16 hrs per day, 777s with the long layover LAX approx 10hrs per day.
777s fly with at least 3 cockpit crew or maybe 4? to LAX and AUH, 330s 2 cockpit crew.
Borghetti knew full well from his days at Qantas how much revenue Qantas derived from 330 operations to/from Perth.
