Hi. I'm puzzled about why I am losing money from my airline over the last several months with all profitable routes and planes? They are all old, leased aircraft, but I thought costs were taken into account when calculating aircraft and route profits. And anyway, half the leasing costs were paid up front and only when I had cash available (except by mistake for one plane after which I let my balance rebuild - which it seemed to be happy to do in the first few months).
