Do you foresee BA LH commands coming down from the nearly double decades?
As has been said before. There was a very significant spike in recruitment of cadets in the early 90s. These pilots will now be approaching 50 years of age, and already on the top pay scale. They almost exclusively occupy LHS LH. There are hundreds of them, and I wouldn't foresee them going anywhere, anytime soon.
Just as we move out of one period of 'stagnation', another is about to begin.
So I would guess around 2030 before much changes from what we see today? The chance at that time, of BA looking anything like it does now, is highly questionable.
We definitely have a surplus of pilots at the moment!
