I always thought Flybe/Stobart should have tried Ostend from Southend instead of Antwerp when they first started the SEN services in 2014. They were always going to get slaughtered by CityJet/VLM out of LCY so they may as well have tried something different. I do hope BE start some UK-OST routes sooner or later, I think there could well be a sizeable market there.
