That link to the Irish Times a post or two back from this one, mentions Flybe and Easyjet competition were a challenge for Aer Lingus Regional.
a. Flybe have moved on
b. Easyjet won't compete on EIDW route
So, in my view Stobart pulling out of airline involvement presents the SEN management opportunity to attract new services to SEN to plug that EIDW demand.
Could you see Cityjet plant a flag in SEN. What about FR could they get 800 series in and out (don't know the STOL performance perhaps B737 drivers on here could comment?)
