The Stobart Air SEN operational performance is totally unacceptable at the moment. To announce over three hour delays on the second and third DUB rotations today some eight hours in advance is not the way to go. If you have a seriously unserviceable E195 then you must sub something in and that doesn't mean adding an extra ATR as a sticking plaster. Finding sub capacity at this time of year can be difficult but it's not impossible and they should be doing just that.
