Joe - I can tell you know that there was no active prioritisation of charter business to GLA, schedules to EDI under BAA ownership. The charges and deals were similar at both. The fact that GLA has 6 x based charter aircraft versus 1 x EDI (and both have strong LCC presence with easyJet and now Jet2 at both, Ryanair at EDI) is driven by demand and yields, not airport pricing.
