I am currently "stuck" at Copenhagen and I would like to do my next flight out of the same airport (not using the travel mode).
The problem is, for my a/c there are only 3 flights available and 2 of those are relatively short and the one I want (Copenhagen to Zürich) has ZERO passengers waiting.
So, do I get a penalty for piloting a plane with no passengers? say the a/c is going for special maintenance at Zürich? I don't see that in the penalty list but one never knows

Yes, it is a shame not to be able to take passengers but if there are none to be had (pretty strange for such a route) there is not much this "pilot" can do.
And while at that... does PP ever issues rewards as opposed to just penalties?
