Your hearsay evidence should at least focus your thoughts a little on the pressures at Gatwick right now and never mind outside when at 7.30 am there are the more aircraft waiting to depart of of the single active runway stacked nose to tail along the parallel emergency runway and the taxiway than there are up the road !
I have never said LGW shouldn't get a new runway, it may not need it once BA & Virgin move flights back to LHR and EJ moves in but increasing charter flights to the med is a totally different business plan to what is proposed at LHR.
That being said, Heathrow has managed to build 2 world class terminals whilst being at capacity almost constantly. LGW cannot even provide clean facilities. The place was a disgrace.
