And to assume the company will double in size every few years will lead to disappointment!
Is the plan still to increase from present 205 to 320 airframes by 2018? That could mean a net gain of 1,900 pilots over the next 4 years, assuming 8 crew set / airframe, plus attrition. There had even been talk of 400 airframes by 2020.
Still, 492 aircraft on order including the 120 options is a lot of hiring at some stage, even if the entire current fleet was to be retired by the time of last delivery.
