Flying to Chicago: airports, timing and tips
Chicago is a genuine two-airport city, and the metro code CHI covers both. O'Hare (ORD) is the larger hub with nonstop flights from almost every US city and dozens of international ones; Midway (MDW) is closer to downtown and often has different fares and departure times on the same route. Searching one airport at a time can hide the better option, which is one reason to have an agent price ORD and MDW together for your dates. January to early March and September to early November are the easier months for seats, while summer festivals and the Thanksgiving and Christmas weeks are the tightest. Winter travelers should know that weather delays are more common at O'Hare, so an earlier departure or a longer connection is sensible in December through February. Both airports have direct rail into the Loop, so ground transfer is straightforward whichever one you choose. To book flights to Chicago with an expert who will check both airports, call +1 (323) 800 6001.

Best time to book flights to Chicago
Book your Chicago flight 1-3 months out for the cheap prices, especially if you plan to travel during the popular summer season.
