Could VS in the long run shift all their routes to Heathrow and drop Gatwick? Concentrating the fleet on Manchester and Heathrow then.
Entirely possible if and when LHR's 3rd rwy is up and running. Unlike BA, who also operate at both LGW and LHR, VS does not have a hub at LGW so has no need to stay there if there is availibility at LHR.
