Flight
This is the fastest and most direct travel option. Dubuque (DBQ) has daily flights from Chicago (American Airlines). It's a small airport, so flights can be more expensive than through other airports. There are however, shuttles to/from the airport for several area hotels.
Flight
Flights to Chicago O'Hare (ORD) are a bit cheaper, but it takes about 3 hours to drive from Chicago to Dubuque, so you will need a rental car.
Flight
Cedar Rapids (CID) is the next closest airport, at about 70 miles away from Dubuque.
Flight
Moline (MLI) is 80 miles from Dubuque, but it offers non-stop flights from across the country.
