Pineapple guy has some ideas. Mine is more traditional, but the "haves" will always fight the "have-nots".
Of course I'm talking the age old national list idea. It got a LOT of debate back in the 80's/91 and was well represented in ALPA magazine..the pros and cons. The irony is, as I remember it, that it was usually opposed (by letters to the editor) by UAL, and Allegheny/USAir pilots. Of course TWA, PanAm, and Eastern guys were for it. It went nowhere, of course.
Teamsters head guy, as I understand it, has floated the idea, but has met the usual opposition, particularly from the legal division boys.
It would be a hard sell to airline management, but I have thought some sort of national list with the union taking over training and standardization might work. Many years ago the Merchant Marine had something like this(at least for the great lakes freighters). One was trained and qualified by the union agreements..then you shipped with "whomever". If Cleveland Cliffs screwed up, you took your years and quals to someone else, possibly without missing a beat.
If we could get over the egos and the management worries, I think we could do this. Or maybe some of Pineapple Guys ideas. What we have now is a travesty and harmful to the industry.
As an aside we lose quality pilots due to this. One of the better pilots I have flown with in my career finally said "enough" (after his most recent job loss) and is driving a truck. The airline industry is NOT better off without him. Very few were/are his level of expertise, skills and work ethic. However, due to our system of doing business, he is probably gone for good.
So it goes.
