Who wants to go to JER anyway? It is expensive and the weather is not reliable, the profile of the SEN pax must give an average age of 60+ and two years of Flybe ops at SEN is best decribed as nearly always late, often by a number of hours.
If you visit the SEN thread you can read via LTNman the intentions of Stobards take over of the South east. Pax traffic will be actively pursued. From what I have seen @ LHR. LGW and MAN there is not frieght at those airports and there is a lot of space at STN for more. I doubt MSE is even on the radar,but lets hope next year brings something?
