If that is the case Cityjet would have been a good candidate to take on the BFS and EDI flights that EZY have dropped from SEN; there's a proven market for both routes, filling A319s on occasions (just not often enough).
I can't think that Cityjet management are currently feeling too kindly towards SEN and Stobart. The new Stobart Air Antwerp route is spoiling Cityjet's cosy monopoly there.
