Trafficnotsighted is absolutely spot on. NQY is not sustainable as a daily mainline aircraft route - barely even in summer - and Easyjet will cut and run as soon as any public subsidy runs out. For an earlier example of how this works, see bmi on LHR-JER circa 2007.
A once-daily service would also mean reliance on good timings for business travellers. I wouldn't be betting on the timings being any good for NQY.
