Chicago, the vibrant “Windy City” on the shores of Lake Michigan, is one of America’s most iconic urban destinations. Whether you’re planning a business trip, a family vacation, or a quick weekend getaway, flights to Chicago are frequent, accessible, and available from virtually every corner of the globe. This comprehensive guide explores everything you need to know about booking, choosing, and making the most of your journey to Chicago.

Why Fly to Chicago?

Chicago is a major hub for culture, architecture, food, and entertainment. Home to world-class museums, the Magnificent Mile, Millennium Park, deep-dish pizza, and a thriving arts scene, the city welcomes millions of visitors each year. Its central location and excellent transportation links make it a top choice for both domestic and international travelers.

Chicago’s Airports: O’Hare and Midway

Chicago is served by two major airports:

  1. O’Hare International Airport (ORD): One of the busiest airports in the world, O’Hare handles the majority of international and many domestic flights. It’s a hub for United Airlines and American Airlines, offering direct connections to cities across North America, Europe, Asia, and beyond.

  2. Midway International Airport (MDW): Located closer to downtown, Midway is a popular choice for domestic flights, particularly those operated by Southwest Airlines. It’s smaller and often less crowded, which can mean shorter wait times and easier navigation.

Both airports are connected to the city center by public transportation, taxis, rideshares, and shuttles, making your arrival and departure hassle-free.

Booking Flights to Chicago: Tips and Strategies

1. Start Your Search Early

Airfare prices to Chicago can fluctuate based on demand, season, and events. Begin looking at least 1–3 months before your intended travel date. For peak seasons (summer, holidays, major conventions), book as early as possible.

2. Compare Airlines and Routes

Chicago’s status as a major hub means competition among airlines is fierce. Use comparison websites like Expedia, Google Flights, or Skyscanner to review your options. Consider flying into one airport and out of another if it offers better schedules or savings.

3. Be Flexible with Dates and Times

Midweek flights (Tuesdays and Wednesdays) are often less expensive, as are early morning or late-night departures. Flexibility can help you score the best deals.

4. Watch for Sales and Special Offers

Sign up for airline newsletters and use fare alerts to catch flash sales or special promotions. Loyalty programs and credit card points can also help you save.

5. Check Nearby Airports

If you’re coming from a smaller city, check for connecting flights via nearby major airports. Chicago’s connections are extensive, but indirect routes can sometimes offer lower fares.
