Looks like T5 didn't have room for all those KJ planes :-). An interesting change in Oneworld topology, as most of the KJ cities are served by the new OW airlines (RJ and MA), along with AY and IB. So it is a move away from LHR as a hub, and to AMM, BUD, HEL and even MAD for those routes. Presumably BA won't try to serve the KJ cities (some of these were mainline BA routes and given to KJ as they were not profitable). It does look like BA is deliberately shrinking in some markets (selling BACON and now dropping KJ). GB is presumably safe, as that is a political connection.
