"There comes a point where they can neither get new recruits (far-fetched perhaps?), nor does anyone from Mainline wish to fly their a/c....for obvious reasons. ... "
Why would they not be able to get recruits if they were paying industry rates?
But if they werent able to recruit then they would either have to stop their expansion or negotiate with balpa or the market to get pilots in.
What difference would being on the MSL make - other than possibly being an incentive to join OS?
IF they cant get new recruits then they need to pay more regardless of them being on the MSL or not.
If they need to post mainline pilots into OS then it must be cos they wish to continue flying their routes - routes on which they must be making money or they wouldnt wish to keep flying them. They then have the choice of raising starter rates into OS or paying Mainline guys to do it - at least with joint seniority they have that option.
Should we call him "Glodon" or "Cobin"
