No it is not cr*p because 1. Most airlines in AE (even non-spams) do it and 2. there are 168 hrs a week, so I still have 168-(19*7)=45 free hours technically LOL.
Your on time performance is sitting at 50%-55% judging from that screenshot. That is piss poor. If that was a real airline your flight cancellation rate would be unacceptably high, the lost revenue and compensation would cripple the airline (something I wish was factored into AE, but, alas, that is for another thread).
So whilst it works in AE, if you are going for any sort of realism i.e. not a spamline, then you need to drastically reduce your utilisation.
