Apparently from September there will be flights available from the redeveloped Salerno Airport to Sicily! See link below.
The Amalfi Coast Will Get an Airport This Summer, But Full Takeoff is Still a Few Years Away
We will be staying in Positano in late September and were planning on flying out of Naples but now wondering if flying out of Salerno would be a better option. Do you think it might be a bit risky / unreliable given it's a new service? Also it seems for now there are only flights available between Salerno and Catania, so there's also that. We had preferred to start our 10 days in Palermo to spend a few days there and visit Monreale before traveling down to Agrigento and across to east coast.
