Georgie, there is only one J41 based in C.T. It does the following routes:
C.T. to Kimberley and C.T. to Upington and back. On Saturdays the aircraft goes to Upington and then onto JHB for an aircraft swop. as far as the crew is concerned, two captains and two F/O's based in C.T. ,with positioning crew from JHB filling in the gaps. As far as the J41 goes its like flogging a dead horse. If it makes money continue to use the thing. Embraer 5 is far as Airlink is going to go...........but then I don't work there anymore so things might be changing. You don't know what Mr Foster has up his sleave.
Anyway hope this answers your question!!!!!
