I built a hub. After that in routes page where are listed all my routes appeared strange symbol at each of routes line. Hard to understand what it is, sand clock? At first all routes had it, but now only few of routes has this symbol. Routes who has this symbol are in grey, routes who don`t have this symbeo are in white background.
I assume if I build a hub, then all my passengers can use this airport as transfer point? I still have not seen any of connecting passengers. no one of my routes loadfactor bar has blue color.
