Chicago Airports & Ground Transportation
One big question for travelers is which Chicago airport to fly into. Here’s a quick guide to Chicago’s airports and how to get to the city from each:
Chicago O'Hare International Airport (ORD)
O'Hare International Airport is one of the busiest airports in the world, serving as a major hub for United and American Airlines. With four terminals and numerous concourses, it offers a wide variety of dining, shopping, and lounge options to keep travelers comfortable. Located about 17 miles northwest of downtown Chicago, O'Hare is easily accessible via the 'L' train's Blue Line, offering a direct and affordable connection to the city center. The airport is known for its sometimes long walks between gates, so wear comfortable shoes! Don't be surprised to spot a plane taking off, it happens every minute!
Tip: Give yourself plenty of time to navigate this massive airport, especially if you have connecting flights.
Chicago Midway International Airport (MDW)
Midway International Airport, located on the southwest side of Chicago, is a convenient option for travelers seeking a closer alternative to O'Hare. It is a major hub for Southwest Airlines and provides a more streamlined and less overwhelming experience compared to its larger counterpart. The airport offers a selection of restaurants, shops and amenities. Getting downtown is a breeze, just hop on the 'L' train's Orange Line for a direct ride into the heart of the city. Perfect for a quick getaway!
Tip: Midway's smaller size means shorter walks, but it can get crowded, so arrive early.
Other airports

Airports like Milwaukee (MKE) and South Bend (SBN) can offer cheaper flights, but remember to factor in the commute to Chicago. Milwaukee is about 90 miles north, and South Bend is about 95 miles east, so plan for a bus, train or rideshare to get you to the Windy City.

Getting around Chicago from its airports is a breeze with a variety of options! Public transportation via the 'L' train is super affordable, while taxis and rideshares offer door-to-door service at a higher price.
