Use to be a fairly regular flyer on the Dornier 328 from LCY to EDI back in the days when Suckling Airways (as Scot Airways on behalf of CityJet for Air France) operated a number of flights on the route.
It's a good little aircraft, the closest that I'll probably ever get to flying on something that seems comparable to a private aircraft. Was one of only a handful of passengers on a number of occasions which added to the feel of exclusivity. It's a little noisy on take-off, but once in cruise just like any other prop.
