With 2.7 million people living in the core and 9.5 million in the greater, Chicagoland metropolitan region, Chicago is the undisputed hub of the American Midwest.

Saint Louis is located 262 miles to the Southwest of the city. Since the departure city’s airport is the busiest in the world, expect reasonable delays. All told, standard trip times take about 1 hour between the two cities.

St. Louis is much smaller, but boasts more free activities than any other city in the United States, aside from Washington D.C. Alaska Airlines, American Airlines, Continental Airlines, United Airlines, and US Airways offer direct, non-stop flights from Chicago to St. Louis each day.

Leaving O’Hare without a hassle

Chicago O’Hare International finally won over Atlanta’s Hartsfield Airport in terms of passenger traffic and total, annual take-offs and landings last year. After a nine year stretch, the southern-based airfield has given way to the extreme growth and expansion of its Midwestern counterpart!

The size and scope of O’Hare can definitely be intimidating to newcomers, but with its vast expanse comes one of the most efficient and passenger-friendly facilities in the U.S. A crucial flight hub for United Airlines and American Airlines, the airport serves 210 destinations worldwide, and over 25% of these are internationally-based. Chicago’s principal airport has been titled the “Best Airport in North America” ten years running, so that speaks volumes about its amazing features and amenities.
