ANstar,
"What they loose - NRT... a market which has been in decline for a whiel
CPT - a market where yields and utilisation are an issue thanks to the ME3
BOM - another market where ME3 capacity to the US has chomped at yields."

You're wrong about CPT, the yields are some of the highest on the network and far outweigh the costs of the relatively poor aircraft utilisation. As mentioned in my post above, the CPT flights are demand inelastic and the excellent load factors in WT, WT+ and F aren't very sensitive to ticket price.
