All things being equal, heres why...
ONE CENTRAL AIRPORT - with airlines concentrating on one site, not 2 as currently is the case GLA and EDI. Cost savings to the airlines = cost savings to the passengers in a general sense.
GLA - Hampered by the available surrounding land and motorway at one end, and river at the other, not to mention the 'sinking runway' which has to be sorted yearly.
EDI - Hampered by general road access. Railwayline at one end and motorway at the other.
There is a motorway called the M9 currently running right past the proposed site. It would need upgraded obviously... This runs from Newbridge in Edinburgh right up to Stirling. The M8 from GLA terminates at Newbridge and joins into the M9... There is also access from GLA to the Falkirk area along the M80 / A80 which would again probably need upgrading, but is available. In fact Newbridge in EDI and the beloved Kingston Bridge in GLA are pure nightmares during rush hour, and the Kingston is a nightmare most of the time - any time...
Cant see your point really... Any new-build aiport or extended airport requires the infrastructure surrounding it to be upgraded too. Any cost-saving in terms of ''one airport in the middle'' (lets face it, the width of Central Scotland is hardly a factor...) is a benefit - any day of the week.
PIK isnt in the frame. Its available now, with ample runway capacity and terminal capacity but sadly isnt favoured by the majors, and only FR in all reality make proper use of it.
''30 miles approx from GLA'' and 25 miles approx from EDI... Do you think the people that live in the east end of London, enjoy having to make their the way out to LHR, whether by car, bus train or tube... when going on trips that determine LHR as their departure point... I think not and its a damn site longer and more complicated for them, as it would be for passengers travelling from EDI or GLA to a new central airport in Scotland.
Cost, choice and frequency of flights is what its all about. Iam sure BA, bmi, flybe etc etc would welcome with open arms 1 single airport. All the airlines could streamline their operations and offer better and more efficient services.
FACT, Simple economies of scale...
Suggest you buy shares in the construction industry if thats the only way you think you might make a fast buck... Will need major infrastructure improvements all round so get in there quick!
