Dan-Air's milk run used to be flown by Doves in the early-mid 1960s, and the routings seemed to vary from one season to the next. Sometimes MAN was included, sometimes LPL. Before BOH was added on the end they finished in either BRS or CWL.
I remember when the Doves were withdrawn, the two of them putting on an amazing impromptu display, beating up the airfield with some crazy flying.
There was also Cunard Eagle Sunday flight MAN-NCL-BGO (Bergen) with a DC6, at that time the biggest aircraft ever to visit NCL. Don't know if it carried local traffic MAN-NCL though.
Anyway, in those days it took half a day to do the journey either by road or by rail.
