Looking at the EZY website, and taking random dates in June 06, there are very few flights listed (one or zero). However, the same applies to Stansted.
IMHO they haven't finished loading the schedules yet. Any reductions of this magnitude would imply a major disaster or change in strategy, neither of which seems likely. If Scotland-London flights are to be reduced, I would expect reductions at Stansted due to increased competition from Air Berlin and flyglobespan.
I believe EDI is Luton's busiest route and must handle around 500,000 pax per annum.
