Update: Only two routes out of DMK worked (DMK-XIC and DMK-KTM), but it might be because I already have flights to the ones that didn't work from separate airports, so maybe it's because of that. However, I tried starting a route to LJG from DMK, and when I leased a second gate there, it still didn't work.... my airline is running low on cash, so I'm really having big problems.
