I think they will be against air travel expansion full stop to be honest. I am sure someone will be a GP member but from my experiences in Local Govt I would say awareness of climate issues ‘politically’ is at an all time high and I wouldn’t fancy any airports regional or city chances of getting any expansion through, without a strong national govt lead prepared to take that on in appeal,
Locally regardless of planners views or financial benefits being positive, politically it would be a huge benefit for a councillor or council leader to go with the public mood.... or they know they will be gone.
BOH are very lucky to have expansion built in on the airside already (FR legacy) and I am sure the access to and from can be suitably ‘greened up’ to get through. BRS vs Greens inroads I can’t see it happening. Bristol is getting greener than Brighton!
