It's very encouraging to hear about Innsbruck for the winter 20/21 season. I am still hopeful - at this stage - that summer 21 will be similar to summer 20 prior to Coronavirus. This could change the longer it goes on, and i'm speaking specifically about BOH.
However, the summer 20 season is going to be pretty much a write off I think. I would be very surprised if any flying on any big scale returns before October - other than those VFR routes like Krakow and Dublin, possibly Alicante.
