I am really enjoying playing with IAD, but now my contracts are full with lots of S CRJs and M Embraer models.
I was wondering about cancelling these, to allow for more profitable aircraft but many of these are established contracts with many plane icons.
I was wondering if the routes ever kind of expire, or run out (I.E. after a certain number of plane icons appear, does the extension no longer occur, and the contract automatically cancel?) please? As if this happens, I would rather wait for this and just not take on any more of these contract types rather than cancelling.
