From a skiers point of view, I am struggling to understand the business model. The majority of ski accommodation is let weekly, mostly Sat-Sat (some Sun-Sun). Powdair indicate they are flying 6 days a week with one ac, so for 4 days they are looking at short break holiday makers (which to be fair tend to be at the high end of the market) and second home owners. Looking at some of the destinations I can't see a high density of second home owners in a limited area of Switzerland.
When you look at other ski regions, airports such as Chambéry and Grenoble are deserted Mon-Fri. Likewise most skiers are aware of airports with poor minimas and don't like the risk, even Jet2 abandoned CMF for last season.
I'm probably out as well!
