Me thinks it is quite a clever ploy by Ms McCall to the Gatwick management to say that just because we have over 50 aircraft based it doesn´t mean we are not loooking at other options so do not try and and blackmail us on fees etc.
Unfortunately I do not believe a third runway at Heathrow or a second at Gatwick or Boris Island etc. will ever be built - kicked into the long grass whoever is in power.
