What the record says about MDW

MDW is one of the later-running airports in the record. When an airport is this congested the cause is usually structural — runway capacity, airspace, or a hub airline scheduling more departures into a peak than the field can clear — and no airline flying from it escapes entirely.

With 40 routes in the record, MDW is a hub, and hubs carry a particular risk: a delay early in the day propagates through every aircraft that was due to fly on afterwards. Morning departures from a hub are reliably better than evening ones.
