If you are flying in, Madison-Dane County airport is a smaller local airport in the city. Milwaukee-Mitchell International is 1 1/2 hours from Madison. Otherwise, Chicago-O'Hare airport will have the most direct, cheap flights and is just under 2 hours away from Edgerton, WI. If you have other friends attending, please try to coordinate your arrival/departure times and rental cars. Ubers/Lyfts are available or there is the Van Galder bus that goes between Chicago and Madison. We will also be having family driving between Chicago suburbs and Madison that can coordinate carpooling.
