Heathrow accessability
But you can connect to LHR via the RailAir links from Reading or Woking....
Good point! does the bus go to all terminals?
Frank - most of the UK airports that link to Schipol are a bugger to get to locally - try Leeds for example - and you have to allow 45-60 minutes to egtthere
Newquay could be linked to LHR but the demand is just not there - same as Dundee, Sheffield, Doncaster, Teeside etc etc
Maybe, maybe not, depends where one is travelling from. As for "no demand", it is true that new availibility and choice creates new opportunities and new journeys, one reason why new roads fill up with traffic so quickly.
However, slot costs make it uneconomical for small regional aircraft; delays, costs and the inability to do quick turnarounds makes LHR unsuited to no frills carriers; and APD adding £28 to any domestic fare; it won't happen, so we will never know.
