If you read my post again that is exactly what I am hypothesising FR being attracted to "major" airports who want a piece of the FR pie.
I fear for PIK at the moment as EDI is about equidistant from GLA and a lot of the routes duplicate each other. A personal choice I suppose if you live on the south side or east end of the city which makes the easiest to get to. I just think we will see FR move to GLA sooner or later and in that respect move into moe "mainline" airports who will lure thme there with free or cheap landing deals.
