Chicago Midway is busy enough that generic airport advice is not enough. The useful question is not only when to arrive, but when to leave from your actual starting point. For MDW, that means working backward from your flight time and adding the local details that can change the trip: I-55, Cicero Avenue, Southwest Side traffic, winter weather and economy parking shuttles, terminal choice, parking or rideshare access, transit schedules, checked bags, TSA PreCheck and the larger buffer often needed for international departures.
Operational details can change, so verify your terminal and travel schedule before departure.
