From the interim Davis commission report i thought it was fairly clear what needs doing, but obviously the remit is to report back after the general election in May 2015......
LHR is bursting at the seams and LGW is heading the same way, leaving aside LCY the other so called London airports have spare capacity but that's not where people or airlines ideally want to fly from.
I just hope (fat chance) that if Davis recommends two runways at LHR & an additional one at LGW that whatever colour the new Government (RED/PURPLE/BLUE) that they have the balls to get on with.
