I echo the above comments about the lack of commercial justification of keeping scheduled flights from LUG.
All the same, I cherish my memories of 99.- "zap and fly" offers on the ZRH-LUG flights back in the days when LX meant Crossair, and the route was served with S2000s and Avro 85s (later found illegal). The flights were often wonderfully scenic, and Crossair served salmon canapés and champagne to all pax in their single-class turboprops.
Even then, it was clear that this was not financially viable - but the SAirGroup didn't care much at the time.
