O'Hare International Airport Construction Update

MARCH 26, 2025

Construction work on the gate used by Denver Air Connection (DAC) at O'Hare International Airport in Chicago is nearly complete! Beginning on Sunday, March 30, DAC flights to and from Dubuque will begin utilizing Gate L27 in O'Hare's Terminal 3. 

This means passengers will have direct access to the terminal and will no longer be transported by bus. We appreciate our passengers' patience and understanding throughout O'Hare's construction process.

You can familiarize yourself with the location of Gate L27 within O'Hare's campus with the map below. Additional maps are also available on the O'Hare website.

Denver Air Connection continues to offer a daily, direct flight between Dubuque and O'Hare. DAC's ticketing and baggage agreements with American and United Airlines allow passengers to purchase trips directly through those airlines, then seamlessly connect to their worldwide destination networks.
