Additionally LS/ZB/FR have all the Spanish and Greek routes sown up so where else would EZY operate to?
The same could be argued for LGW, MAN, EDI and GLA and that's before throwing Vueling and Norwegian into the mix.
For whatever reason EZY just have no interest in serving the Midlands which is a shame as they could still offer a great deal. There's a whole number of un/underserved destinations that could keep a few based planes busy - just look at what they offer from BRS!
