Affordable Flights to Chicago, IL: Find the Best Fares with CheapFareFreak

Finding affordable flights to Chicago, IL, is much easier than travelers might expect. This is because few cities in the United States offer such a wide variety of airlines, routes, and flight times. Chicago serves as a major hub for American aviation. With two large airports, two primary airline hubs, and numerous low-cost carriers, the city ensures that airfares remain budget-friendly throughout the year. At CheapFareFreak, we compare fares across various airlines and dates allowing you to book a flight to Chicago that fits your budget.

Why is traveling to Chicago so convenient?

Located in the heart of the country Chicago has served as a natural gateway for air travel for nearly a century. It offers direct flights to most major U.S. cities, as well as non-stop connections to many international destinations. For travelers, the intense competition among airlines is a significant advantage; when multiple carriers operate on the same route, fares remain low. Furthermore, if your schedule changes at the last minute it is easy to manage as there are often other flights available on the same day.
Most travelers heading to Chicago arrive at one of the city’s two airports. Understanding the differences between them is the first step toward saving money.

Chicago Airports O’Hare vs. Midway

Chicago O’Hare International Airport (ORD):- O’Hare is located approximately 17 miles northwest of downtown and is one of the busiest airports in the country. This is a major hub for both United Airlines and American Airlines. Consequently, it offers the largest number of non-stop routes, including many international destinations. Airlines such as Delta, Alaska, JetBlue, Spirit, and Frontier, along with various international carriers, also operate from here. If you are traveling from a smaller city, O'Hare provides the most extensive range of connecting flight options. Furthermore, due to competition between United and American Airlines on certain routes, you can often find very affordable fares.

The CTA Blue Line (train) runs directly from the airport terminal to 'The Loop' with a travel time of approximately 45 minutes. Therefore, even if you choose not to rent a car, O'Hare remains a highly convenient option. Since ground transportation costs and fares are subject to change, it is advisable to check the current CTA rates before your trip.

Chicago Midway International Airport (MDW):- Midway Airport is smaller in size located closer to the city, and generally easier to navigate. Situated about 12 miles southwest of downtown, it serves primarily as a hub for Southwest Airlines, with other carriers also operating flights depending on the season. Travelers who prefer to reach their gates quickly and spend less time in security lines often choose Midway. For domestic routes—where Southwest Airlines plays a key role in setting fare prices Midway can offer very budget-friendly fares. The CTA Orange Line connects Midway to 'The Loop' (Chicago's central downtown area) in approximately 25 to 30 minutes. This is one of the fastest ways to travel from an airport to the downtown area in any major U.S. city. Since the ground journey to or from Midway is shorter and more affordable, the total cost of your trip might end up being lower even if the airfare to Midway happens to be slightly higher.

Which airport should you choose?

The smartest approach is to search for flights to both airports. It is possible that on a given date, the fare to O’Hare might seem standard, while the fare to Midway is significantly lower or vice versa. Using a tool like 'CheapFareFreak,' you can compare Chicago’s airports side-by-side. This allows you to make an informed decision by considering not just the airfare, but also the time and cost required to travel to or from the airport.

Airlines flying to Chicago

The presence of many different airlines makes it possible to find Cheap flights to Chicago from various cities. Here is how the major airlines fit into your search for fares:

• United Airlines: This is the largest airline at O’Hare Airport, boasting an extensive domestic network as well as numerous non-stop international flights. As a major 'hub' for United, the airport allows travelers from smaller cities to reach destinations across the country or abroad via Chicago. With many daily departures, it is easy to find a flight that fits your schedule.
• American Airlines: This is the second-largest airline at O’Hare Airport. It faces stiff competition on routes originating from the East Coast, Texas, and the Southwest. Since American Airlines and United Airlines often compete with each other on the same routes, fares can be quite low especially if you book a few weeks in advance and remain somewhat flexible regarding your travel dates. 
• Southwest Airlines: Southwest Airlines is a prominent carrier at Midway, known for its flexible change policy and affordable domestic fares. With a straightforward, easy-to-compare pricing structure, it has long been a favorite among budget-conscious travelers. Furthermore, it offers flights to many destinations that other airlines can only reach via connecting flights.
• Delta Air Lines: A reliable full-service carrier, Delta operates frequent flights from its primary hubs, including Atlanta, Minneapolis, Detroit, and Salt Lake City. On routes where it competes directly with United and American Airlines, Delta’s fares are often highly competitive. It is an excellent choice for travelers who prioritize in-flight comfort and high-quality service.
• Alaska Airlines: A strong option for those traveling from the West Coast, with flights available from cities such as Seattle, Portland, and San Francisco. Alaska is frequently praised for its exceptional customer service. It also offers good value on long-haul routes, including those to Chicago.
• JetBlue: A popular choice among travelers in the Northeast, particularly in New York and Boston. Offering comfortable seating and affordable fares on routes connecting these cities to Chicago, JetBlue proves to be an attractive option. Frontier Airlines: This is a 'low-cost' airline that offers very low 'base fares.' However, when calculating the final cost, you must also account for baggage fees, seat selection charges, and other additional expenses. On paper, these airlines often appear to be the cheapest, so they should certainly be included in your search. That said, rather than looking solely at the base fare, you should compare the total cost.
• International Airlines: Many international airlines operate out of O’Hare Airport, including Air Canada, British Airways, Lufthansa, Air France, Emirates, and several others. Travelers arriving from abroad can often fly directly (non-stop) to Chicago. Meanwhile, those traveling from other cities within the United States can take advantage of affordable fares by combining a domestic flight with an international carrier.

When booking tickets, do not just look at the headline fare, instead, compare the total cost. This is the most reliable way to avoid unexpected additional expenses. Sometimes, a low base fare combined with baggage fees can result in a higher total price than a ticket that appears more expensive upfront but already includes a baggage allowance. Therefore, it is beneficial to understand the full picture before making a booking. 'CheapFareFreak' simplifies this process; it allows you to compare different airlines side-by-side, helping you determine which option offers the best balance of price, timing, and convenience for your trip.

When is the best time to book the cheapest flights to Chicago?

Chicago experiences significant seasonal variations, which have a greater impact on airfares than almost any other factor.

The Best Time to Find Cheap Flights

The winter season—particularly January and February—is generally the most affordable time to visit Chicago. Although it is quite cold and strong winds blow in from the lake, hotel rates and airfares often drop once the holiday crowds have dispersed. Travelers who are prepared to dress warmly can enjoy a fantastic trip at a lower cost. Furthermore, museums are less crowded during this time, and wait times at restaurants are shorter. Early spring and late autumn also offer a good balance of reasonable fares and pleasant weather.

When Might Prices Rise?

Summer is the peak season. Warm weather, festivals along the lakefront, and major events often lead to fully booked flights and hotels, driving up prices. During large-scale events such as 'Lollapalooza' in early August or the 'Chicago Marathon' in October prices tend to spike around those dates. Therefore, if your schedule is flexible, you can avoid these major events and reduce your expenses by adjusting your travel dates. Prices also tend to rise during the holiday season, partly due to the popularity of seasonal markets and festive decorations throughout the city.

The best time to book

For domestic flights booking one to three months in advance often secures the best fares. However, this timeframe can vary depending on your departure city and the time of year. Flying mid-week specifically on Tuesdays and Wednesdays is generally cheaper than traveling on Fridays or Sundays, as the latter days see higher demand from weekend travelers and business commuters. Instead of checking prices manually every day, you can set up a 'fare alert' on CheapFareFreak; this allows you to monitor a specific route and book as soon as the price drops.

Tips for getting the best deals on flights to Chicago

By adopting a few habits, you can significantly reduce the cost of your trip to Chicago.

Be flexible with your travel dates: Shifting your departure or arrival date by even a single day can lead to significant differences in airfare. Comparing prices across an entire week or month will help you identify the most affordable options.

Always compare different airports: For instance, in Chicago, O'Hare and Midway often offer different pricing for the same trip. The cost difference can be substantial, especially when you factor in the expense of traveling to or from the airport.

Check other nearby airports: If a major metropolitan area is served by multiple airports, look into all of them; you might find a cheaper alternative that is just a short drive or train ride away.

Consider combining one-way tickets: On certain routes, purchasing two separate one-way tickets, potentially from different airlines can be cheaper than buying a standard round-trip ticket. This is often even more cost-effective when low-cost carriers are involved.

Be mindful of baggage policies: If you choose an airline that charges extra for carry-on luggage, traveling with less baggage can make your trip significantly more budget-friendly.
