BMI CEO Wolfgang Prock-Schauer has already said he wants to pull bmi aircraft off the regional routes and use them to focus on the *A hubs.

That, of course would free up slots at LHR for *A longhaul.
As welcome as a NCL-FRA service would be, that depends on slot availability at FRA - which isn't good. I can't see a single daily ZRH working. And they'd have to be careful apreading themselves too thin (DUS and CPH are already not frequent enough to act as workable hubs. If they added ZRH and MUC - even double daily - that would be about as much use as a chocolate teapot).
The Embraers are a perfect size to operate 3x daily to a *proper* *A hub (which, with the best will in the world, CPH/ DUS/ BRU aren't). If we had two hubs - one of FRA/MUC/ZRH
and BRU, they could really take on KL/BA/EK.

Bear in mind also that MME airport has just won a high court appeal against bmibaby from when the latter pulled out of an agreement to base several aircraft at from the airport till 2014. Baby now has to pay MME £11m in compensation.
Instead of paying the compo, why not just set up shop at MME and operate 5x daily to ZRH, MUC, FRA, LHR, BRU and JFK.
