wouldnt surprise me if BA concede at LGW then once Easy rule surpreme there, circa 5 years time, still massive apptite for expansion, no more available at LGW then decide, 'well, BA roled over nicely, well do the same at LHR' then bingo, they are there. BA must bite the bullet and stay at LGW because, long haul maybe on the horizon, never been done before, but basic cost model cheaper etc, so could be in the future.
