Odd, and probably warrants an explanation.
Yield versus maintaining market dominance in the LON-HKG market versus MAN will accept whatever is sent their way? A new B77W isn't *that* bad a product.
LGW yield may even be lower hence needs to go daily to be credible in market whereas MAN can be slightly constrained and more profitable?
Either that or LGW makes more money than MAN which would not be my first view, but outside of Cathay Towers, who knows?
