I'm an ex-mil 4-jet AT/AAR QFI with a few thousand hours and 20 years or so of world-trotting - but the idea of being locked in a broom cupboard with a stranger watching computer screens for 6 hours doesn't appeal, so my ATPL is purely used for GA instruction and I'm quite happy to let the youngsters 'enjoy' what nowadays passes for an airliner-driver's existence. No chip on the shoulder, therefore! I might have though about applying to an airline it if the lifestyle was still more like it was when James Robertson Justice was flying his Stratocruiser in 'Out of the Clouds' - but sadly it isn't.
Here's a suggestion. Why not specify a minimum qualifying period for the pilots employed by an airline before they then compete for the LHS on merit? No fast-track for ex-pointy jet drivers, no automatic consideration for long serving Hamsters (or whatever the current term is). Just do the qualifying time, then let merit selection be the LHS determinant.
Similarly, bidline. Why not factor it so that the only rostering during the minimum qualifying period would be automatic; therafter as seniority increases, so would bidline rights. But they should never exceed 50% choice, 50% auto-roster.
But I don't suppose that BALPA would be particularly happy....
