Flight
Chicago is typically cheaper to fly into, even though Milwaukee has its own airport. It is roughly an hour and a half drive from Milwaukee (depending on traffic).

Another Chicago airport option, although it is typically cheaper to fly through O'hare, you may be able to snag a cheap ticket with some airlines with this airport.
