LHR is the best option but not politically so LGW will get the nod.
LGW won't get it, it's a stitch up for LHR to allow the "independent" commision to take the flack when the very tough and correct decision that the last Labour government rightly made is re-instated. No one in the business community except Gatwick Airport ltd is asking to expand LGW.
Lydd and Manston may not be ideal but could take some pressure off Gatwick and Heathrow.
Manston is closed, no one wants to fly from there, same with Lydd. The market, i.e. most of us, decided that.
