DarrenMoore - when a new master contract comes in, check on it the proviso's, some are specific, ie. cargo maintenance as you've found. Check that your apron goes from all stands to the terminal, and is linked to all plane maintain etc. otherwise the pax flights won't be offered. Also needs taxi rank, bus stop and train station to be near terminal entrance. Basic thoughts, gets you hooked initially but can become tedius as you go along until your first big jet lands and then is there any point going on!?!
