Not wanting to distract from what is a BA thread but comparisons can be useful and the point made was that the red and yellow machine has weekends off as part of a scheduling agreement rather than being miserable for a number of years until seniority becomes your friend.
That sounds like a very sensible rostering solution. If BA pilots were given Carte Blanche to design their own agreement something like that may well work better for future generations.
The problem is BA doesn’t work like that, and in a seniority system you have to accept a period at the bottom. Which means years of majority weekend working.
