Have you looked on kayak or itamatrix for your other Sardinia routings? It may be time of year dependent I can imagine there being more restricted flights outside tourist season but if you can fly direct from the UK I'd have thought odds were good of there being something.
Try easyJet or Germanwings for flights from Olbia or Cagliari. The odds are that they are summer only, otherwise you'll be looking at flights via Rome
If you can put up with Ryanair they also fly from some German airports to Algheroand Cagliari during the summer.
You can get info on flights on the Sardinia.com website but it will only be during the summer.
Thank you all for your input. Should have mentioned my travel month is September. Found a Condor non stop flight from Male to Frankfurt. Will then travel by train to Lauterbrunnen/ near Interlaken, which is one of our destinations and from there back to Zurich. Edelweiss (thank you Chrell!) flys nonstop Zurich - Olbia. Heard to many horror stories about Ryanair...so better not. Getting so excited. Love all this holiday planning.
