When Easy left EMA they were all about building up Gatwick. The fundamental problem is that EMA is too close to Birmingham - it will continue with a largely leisure and freight operation but little more. it really is in the right place for freight- the so called "golden triangle" (truck to anywhere in the UK in 4 hours).
As posted elsewhere the small aircraft business travel activity is not sustainable these days unless there is sector specific support ( e.g.oil, banking) or a public subsidy.
