Denver Air Connection’s O’Hare Gate Updated

MAY 15, 2025

Starting Friday, May 16, Denver Air Connection’s flights to and from the Dubuque Regional Airport will be served by a new gate at O’Hare International Airport in Chicago.  

The Denver Air Connection (DAC) gate will shift to Gate G21 within Terminal 3. DAC had previously used Gate L27, also in Terminal 3. 

Gate G21 is in a more centralized location within both Terminal 3 and the overall O’Hare campus. It offers easy access to gates used by American Airlines. It also is geographically closer to Terminal 1, where many United Airlines gates are located. 

Friday, May 16, also marks the date of the schedule change for DAC’s flights at Dubuque. Flights from Dubuque to O’Hare will depart at 7:50 a.m. daily, landing at O’Hare at 8:45 a.m. The return flight will depart O’Hare at 5 p.m. and arrive in Dubuque at 5:55 p.m. 

Additional questions or assistance requests can be directed to Denver Air Connections’ Customer Service Department at 866-373-8513.
