Skipness one echo
Not a chance that one off the alliances will be forced to move from LHR, you either move all of them to Boris Island or they stay at LHR with or without a new runway.
LGW needs a second runway for its own growth, even if the likes of Norwegian based its entire planned 787 fleet at LGW it would have little effect on LHR demand.
I just hope that the people who get to decide on the Davis report understand that LGW serves a very different market to LHR, both a prime assets to UK investment, jobs and access to international markets.This should never have been a one or the other debate, for the government the political cost will be the same whether they build at either airport or both, the job boost will clearly by greater by doing just that.
Scrap HS2 build HS3 and green light both LHR & LGW but not a cent of public funds and that includes immediate infrastructure costs on the associated M25 & M23 motorways.
Medium term pollution will decline, the latest generation of petrol engines, stop/start technology,hybrid and all electric cars will see to that.
