About the CDA


The Chicago Department of Aviation (CDA) administers all aspects of Chicago's two major airports: O'Hare and Midway International Airports. In addition to managing world class airports in Chicago, the CDA is one of the regional leaders in business, employment and sustainability. The CDA has made a commitment to the Chicago area community to be a steward to residents, visitors and the environment.

The CDA's central purpose is to:

  • Ensure safe and efficient travel through O'Hare and Midway International Airports
  • Successfully implement the O'Hare Modernization Program (OMP)
  • Enhance economic activity and job creation of O'Hare and Midway International Airports
  • Manage airport tenant and concessions license agreements; ground transportation facilities; financial administration; research, planning and development activities
  • Integrate airport-specific, sustainable planning and practices in design, construction, operations, maintenance and daily airport functions

The CDA is self-supporting, using no local or state tax dollars for operations or capital improvements at O'Hare and Midway. Together, Chicago's airports generate more than $45 billion in annual economic activity and create 540,000 jobs for the region.
