Heh heh! Perhaps.
One thing I have never understood is why is GA (the light end, not BizJets) regarded as such a nuisance at bigger airfields? I understand concerns about approach traffic etc. - it's no mean feat mixing SEPs with 757s and Dash-8s - but surely this is not the sole reason? The ATC controllers at EDI do a wonderful job of mixing light aircraft with the heavies and it all works well.
What was Signature's reason for the 840% hike in price? Did they give a reason?
