tamalai is closer to the money than you think little cheese - although I understand your scepticism.
The hard facts are that, with the growth forecasts for the company, it will be a gargantuan task indeed to man all the pumps. With impending pilot retirements, and the arrival of new equipment, the training machine will be hard pressed to cope. We know what happened when the training pressure became a bit to much to bear on the 'bus fleet recently. It could easily happen again if previous lessons have not been learnt.
The area that will need to be addressed is how to expedite suitably qualified S/O's to their upgrades so they don't get leap-frogged by DE F/O's (paxfleet) should it come to that. Oh no not another round of bypass pay! Then how do you reconcile that with the current freighter folk and their payscale?
I suspect a few 'what if' scenarios are being run at the moment to try and find the most expeditious way to man the expansion. My bet is that there will be a bold move shortly to sort it all out once and for all. Probably encompassed within the 60 retirement deal/scenario.
Bottom line is share performance. Grounded aircraft due to crew shortages will not reflect well on the end of year balance sheet. Shareholders will want results and not excuses.
