Maybe BA is not too happy with Aer Lingus' intentions to base A330's out of LHR?
BA may be rocking the Oneworld boat saying that it's not the sort of move into their own back yard expected of a Oneworld partner????
Willie Walsh I expect would tell BA to **** off if they want to play that game, call their bluff, and would rise to the challenge with increased vigour!!!
Why should EI keep feeding BA longhaul at LHR when they have the opportunity of doing some of it themselves??
