newswatcher: maybe a stupid question but, with all these changes, what is the reason to keep the Miami flight as the only BA one in/out of T3?
I used to subscribe to the "T4 is full" theory. But I've heard that it's more Machiavellian than that.
T3 houses
oneworld partners AA and CX. It also houses Star members SK and UA, as well as other doughty competitors such as VS. If BA operates some flights from T3, it gets a say at the terminal users committee (or whatever it's called) thereby enhancing OW's clout at T3 and dissuading the others from stitching up AA and CX.
It's so political that it definitely has the ring of truth about it. In my view, anyway.
