In reality it most likely didn't.
The way the flying programme was planned @ LPA they needed the flexibility, but, in any case, our current contract had the ability to move our pattern one day back or forward at will at the planning stage. Doubt it will gain them much operational flexibility that they didn't have at AGP/HEL/(LGW)
But, as demonstrated over the years so ably by Ryanair, when someone volunteers to bend over, why not take the opportunity
to shove it up em
There was talk of 200 or so pilots being recruited this Winter (inc 787) & it seems even the deterioration of the contract still leaves it more attractive than China for most of us.
Scandi colleagues who joined specifically because the contract facilitated commuting , may find the variable roster something of a deal-breaker.
Time will tell if they have misjudged this up in Fornebu.
