Edinburgh's quite commercial too!!
Just about every scottish financial institution has their headquarters in Edinburgh not to mention the Scottish Parliament, the Scottih Office etc etc.
Wouldn't dream of trying GLA to EDI by public transport again.....done it once....nightmare......
Can take 2 hours by car too if you want to get to GLA for the Continental to Newark. Have to go through TWO rush hours and accross the most congested road bridge in Europe! Then of course there's the M8 grass cutting in Summer but that's another bulletin board altogether ;-)
It's only a hour shuttle from London to Edinburgh but the point is we need a direct flight to the US from Edinburgh.
Nothing more infuriating than getting the 6:40am shuttle to LHR and then flying back north over Scotland 3 hours later on your way to the US!!!
