but there were other reasons like different socio-economic profile (10% higher share of A/B at LGW), larger base of potential passengers with UK citizenship (22 million vs. 10 million), and we may also add the differences between the two regarding public transport in to London.
Live in Surrey
Base of potential passengers being bigger at LGW ?
Base means nothing unless there is a propensity to fly and solely use the airport?
Live in Surrey so supposedly am in LGWs catchment area as are friends and neighbours. Of those who actually fly, they are just as likely to fly from any London airport and include Bournemoth into that calc as well.
I would say LHR is the airport most use despite LGW being a lot closer then LGW just above STN with LTN and BOH coming behind but even BOH does ok.
I must admit not to knowing anybody who flies more than once a year who will soley use one airport.
