www.isp.il.us and click on firearms/FOID and then on Chicago under municipal ordinances. Chicago ordinances say you are not in violation if you are transporting a firearm or ammunition while engaged in interstate travel in compliance with 18 U.S.C.A. 926A. If you are in the city over 24 hours it is assumed you aren't engaged in interstate travel. In most of Illinois you are O.K. transporting a firearm unloaded and encased even if a loaded magazine is in the case, it can be in the passenger compartment and courts have ruled that a console is a case. Having said that local ordinances on transport can mess you up and they are most likely in the Chicago area. BTW people do fly in and out of Chicago with firearms, it isn't like New Jersey.
