Pax numbers on DND-STN have been heading backwards and last stats show average load of 57%. The existing SEN routes all have loads of 62-63%, which is clearly better including on CAX which is both a brand new route with somewhat faster link to London area by train. On that basis I can’t see what harm shifting to SEN would do, and can’t see the benefit of upgrading to an ATR unless they’ll be attempting to boost demand by lowering fares.
