Its shows the importance of EI
The whole crack story with EI etc just shows the strategic importance of the airline to Ireland. Heathrow despite the recent growth of EY etc is still vital as an airlink/hub to Ireland. Maintaining the connectivity is absolute. If BA or anyone finds a better use for the slot.......it's gone to new routes say "SFO" or wherever.
Obviously there is a bigger game going on in the background.
