The Chicago Department of Aviation (CDA) administers all aspects of two major airports – Chicago O’Hare and Midway International. The CDA is also charged with the management of the O’Hare Modernization Program (OMP), which will overhaul O’Hare’s intersecting runway system into a parallel runway configuration.

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 International Airports. Together Chicago’s airports generate more than $45 billion in annual economic activity and create 540,000 jobs for the region.
