Adria has confirmed that it is looking at two of Skywork's former routes from BRN, one of them LCY. They are about to start their new Saab 2000 operation woth six aircraft and should have plenty of capacity left as only 2 or 3 aircraft appear to be scheduled so far. It should be noted, however, that they will begin to serve SEN from PAD soon, so SEN-BRN would be another logical choice.
The same (Austrian) source also reports that BACF is looking at VIE as part of their 2019 expansion.
