CBS Chicago reported that the airport tower at Chicago-Midway was closed at 2000 UT 17 March 2020, with essential functions being transferred to Chicago TRACON. Flights will be able to continue.
Midway is the largest of three Midwest hubs used by Southwest Airlines. The airline has been cutting flights as demand has sagged in recent days.
