Of course its on the wrong side of Glasgow. It means they are losing marketshare in areas much closer to the centre of Glasgow than Edinburgh in places like Lanarkshire and even marginally closer places like Stirling and Falkirk. To be honest, I am marginally east of Glasgow and could probably get to EDI quicker driving during rush hour.
Not a surprise they want to grow at GLA though with the likes of the Bergen route given the rubbish service to Scandinavia and that is where they are based. Hope it continues.
