The Chicago Department of Aviation (CDA) last week restricted O’Hare International (ORD) and Midway International (MDW) airports to ticketed passengers and airport employees as a response to the persistence of the COVID-19 pandemic.

“In order to ensure the safety and security of our valued passengers and employees, access to airport terminals is restricted to ticketed passengers, those assisting passengers, badged employees and others with legitimate airport business. Enforcement of these restrictions will begin… Friday, July 31, 2020,” the CDA said in a press release.

CDA security and the Chicago Police Department (CPD) will set up a nightly checkpoint at each airport’s CTA stops. Travelers must show proof such as a boarding pass, while employees must show their badge or ID.  Limited access will also be allowed for those assisting passengers.

The CDA added the restrictions have been added at other U.S. airports, including Hartsfield–Jackson Atlanta International Airport (ATL); Baltimore/Washington International Thurgood Marshall Airport (BWI); Los Angeles International Airport (LAX); La Guardia (LGA) and John F. Kennedy (JFK) International Airports in New York; Newark Liberty International (EWR); and Philadelphia International Airport (PHL). ​
