It's called supply and demand - more demand means cheaper costs and has nothing to do with your interpretation of the figures I'm afraid.
EDI has recorded more demand during the winter months
for the past few years. In fact it has been BAA's busiest Scottish winter airport for about half-a-decade. It is currently BAA's busiest 2007 year round airport. So if more demand were to apply, BAA's EDI would should be offering 28.5% discount?
