I think this is a sure sign that EIR's days are numbered at SEN, which is a shame as pax numbers have been increasing and the route now seems to be exclusively 72s.
It is interesting though for a couple of reasons. Firstly, as noted, this appears to be on BE metal rather than Stobart Air. Secondly, it is a route also to be operated from LCY which shows a willingness by BE to operate from both; many said BE at LCY killed off any hope of BE at SEN. So, it is quite feasible that EDI and possibly BHD could follow. Possibly also the PSO to Dundee, unless the rules stipulated only STN could be used.
I can also see them doing JER if EZY do call it a day at the end of the summer
