Recruiting
Now we have the ultra low cost airlines that cannot? spend like airlines used to spend (just like GA) and cannot afford to train a continuous stream of transient pilots who are using this as a "stepping stone" to the highly paid skygod job somewhere else.(just like GA.) Nor can they afford to have the "bitching Bertha's" that have been so apparent here. (the ones who flew those "clapped out" aeroplanes. The next aeroplanes they fly will also be "clapped out")
So the airlines are now low paying and very selective. They need positive, enthusiastic pilots who will accept bonding and a right hand seat for a (guaranteed) few years. I think the MPL will be significant here. Maybe contract pilots. Maybe CPL's in the Right hand seat?
And those airlines that commit themselves to long term training and recruiting, and make a commitment to their trainees will have less staffing problems.
The long term regional pilot will come back, as will the long term GA pilot.
When the bludging airlines stop stuffing it up.
