I believe that a Stobart vehicle has bought the 3 E195s from their previous lessor, essentially they are stuck with them.
I have suggested elsewhere that Stobart might put their planned flights for sale via the Ryanair website but not a true franchise as with Aer Lingus or flyBe. Im sure there are a lot of reasons that Stobart may not wish to do this, but the exposure it would give STK flights would be useful and it would further Ryanair's aim of becoming the Amazon of travel.
Im not saying this is something that Stobart should do, but it would allow them to avoid having to launch an entire customer facing brand/wbesite/booking engine should the flyBe arrangement end.
