My understanding is that Loganair are dropping the Saab 2000s (and Dornier 328s) asap and are replacing them with six (IIRC) Embraer 135/145s - which are no good for IOM-LCY as either too small or not certified. As I understand, the ATR42-600s will join at at laterp oint as a replacement for the Saab 340s. So it appears the Loganair Saab 2000 will need to be replaced sooner than later by BACF.
