This airport is closer but there is no commercial service here. ORD or MKE is best. I personally like MKE for commercial flights if there are direct ones.
There are no commercial flights from here. This is mainly a private charter type airport
It's definitely close to Great Lakes than Ohare but I don't know if Waukegan had many (if any) commercial flights. Waukegan is the next town north of Great Lakes.
