Aircraft Noise Complaints


Official aircraft noise complaints include all complaints submitted via telephone to the Midway Noise Hotline, via our online form, or via the CHI311 mobile app. The complaints are then forwarded to the Chicago Department of Aviation (CDA) for tracking purposes only and will be included as data in the Airport Noise Management System reports.

There are three official ways to submit a complaint:​

Submit Complaint via Telephone​

The CDA maintains a toll-free noise hotline (1-800-914-8537 for suburban communities or 311 within the City of Chicago) for citizens to express their concern about particular aircraft events or aircraft noise levels in general.


Submit Complaint via Online Form

In June 2009 the City of Chicago launched a webpage where complaints may be entered directly online. The link below leads to the City's 311 System where one can fill in information about a noise event.

Submit Aircraft Noise Complaint Online

If you are trying to enter a complaint online and are receiving an error message, please call the Noise Hotline and let the operator know the webpage is down.
