No, I think we're seeing the effects of the same flights being offered at EDI for £100 or so less than can be offered at GLA. Quite why that disparity exists is anyone's guess of course and we have all speculated already.
What flights are you talking about here.. ive never heard any mention of there being a disparity here? I've just been pricing up flights to Krakov for the end of the summer, and Lufthansa from Glasgow is coming up as one of the cheapest option, often cheaper than Ryanair direct from Edinburgh!
Is there any reason for EDI to hang onto it's freight services for example when the freight itself is rarely specific to Edinburgh and a considerable amount travels by road from other areas of Scotland ?
Most freight flights operate in the evening or at night, so I'm not sure how this helps with capacity. Besides, the main limiting factor at the moment is terminal capacity, followed by stands, but there is plenty of room for new stands if needed.
