From a completely empirical observation, and being aware that ticket prices are hardly an indication of cost to the airline, the price of my usual AMS-ZRH-LUG R/T basically doubled when the wetlease went from OS to JP.
My conspiracy theory was that LX tried to make flights to LUG uncompetitive with a clear plan to scrap them sooner rather than later. The demise of JP probably just accelerated the process, I guess LX aimed for 2020 when the rail traffic situation will be stable. But as I said this is all pulled out of thin air.
On a related note, among the hysterical reactions of local politicians, a member of a small party spoke about focusing efforts to expand ZJI (Locarno) airport, which AFAIK can service jets (A320 and such). That could be interesting, and would open the LCC market (Milano North airport anyone?).
EDIT:
Look at this!
