You are certainly correct to highlight that caveat, and your point about some transatlantic sectors is, was and will be probably correct too, I'm thinking specifically NYC, LAX, SFO, where CW in particular is probably all that matters. But there is second layer for transatlantics - India is traditionally second or third best market, but it isn't point to point traffic, it's all those Toronto or Dallas to Bangalore sort of flights that matter. TLV and South Africa are also in the top 5 on a similar basis. And that's where WTP becomes hugely important, First not at all important. Air France worked this out some time ago, but BA seems to have a broader take on the issue. But yes, you can't run an airline of BA's complexity of the basis of these broad statements, there are many fine layers.
