Flight from Chicago Midway Airport to Montreal

ScottFlew with Air Canada-Jun 2026

Make sure you have enough time between connecting flights so ½ of your baggage doesn't miss the flight and take another 24hrs to show up

valerieFlew with Air Canada-Jan 2025

“Meal” usually means more than a light snack. I thought what they served was an appetizer not the total meal. So I’d eat before or bring food.
