Denver Air Connection’s daily flights between the Dubuque Regional Airport and O’Hare International Airport in Chicago will come to an end in early 2026, following decisions by the Dubuque City Council and Dubuque Airport Commission this week. At its meeting on Monday, Dec. 15, the council voted to direct the airport commission to end the service agreement with Denver Air, effective Jan. 15, 2026. Denver Air has agreed to that service termination date. Passengers who booked flights after Jan. 15, 2026, through American, Delta, or United Airlines, or an online travel agency such as Expedia should contact the airline or agency for re-accommodation or refund. Those who booked through Denver Air only to/from Chicago after the morning of Jan. 15 will be refunded or they can contact the customer service department.
