There's a subtle difference between Italian charters and a scheduled operation - the italian charters have interferrence outside of EUJ when inevitable problems occur which does not always give the best solution.
Left alone, euj ops can properly trouble shoot problems on their OWN routes and come up with workable solutions.
Regarding loads, there are many established routes that carry less than EUJ's first flights and it must be factored in that people will take a while to pull theselves away from the better known carriers and try something new.
Why not give a positive response to a new scheduled airline and give it time to prove it's worth?
