speedtwoten, with the apparent hole MAS have dug for themselves - by allowing their EXPERIENCED Captains to depart - what did you think the solution was going to be, other than to replace EXPERIENCE with EXPERIENCE?
Upgrade F/O's who are not yet ready, in terms of experience?
Further, I doubt that - even if that option were exercised - the training department could handle the volume required, nor do it quickly enough to prevent the "re-scheduling" from eventually becoming ongoing cancellations.
MAS has cut off their nose, to spite their face, by allowing their long term Captains to leave the company, rather than increase their benefits to retain them - a decision they are going to regret, and one that is going to cost them FAR MORE than they have saved.
