O'Hare International Airport

O'Hare International Airport (ORD) is not merely an airport, but a veritable city within a city and one of the busiest aviation hubs in the world. Located 27 kilometres northwest of downtown Chicago, it serves as the primary aerial gateway for the entire Midwest of the USA. Since opening after World War II, the airport has grown into a colossal complex that welcomes and sends off tens of millions of travellers annually, connecting Chicago with hundreds of destinations across the globe. O'Hare is renowned not only for its scale but also for its complex yet efficient operational system, allowing it to remain a key element of the global transport network.

One of the main features of O'Hare Airport is its role as the largest hub for United Airlines and the second most significant for American Airlines. This ensures an incredibly extensive route network for both domestic and international destinations. The airport consists of four active passenger terminals (1, 2, 3, and 5), between which an automated transit system (ATS) operates, allowing passengers to move quickly.

For the convenience of travellers, the complex offers a multitude of services: from standard shops and dining venues to unique options such as a yoga area and art installations. For instance, the walkway between Terminals 1 and 2 features the famous light installation "The Sky's the Limit"—a multicoloured neon tunnel that has become a hallmark of the airport. Transport connections to the city are excellently developed: downtown Chicago can be easily reached via the metro (Blue Line), which operates 24 hours a day.

O'Hare International Airport (ORD) is one of the main transport hubs in the USA, and there are numerous ways to reach it from Chicago. Your choice will depend on your budget, amount of luggage, and available time. Below we review the most popular options so you can plan your journey as comfortably as possible.

The most economical and reliable way to get from the city centre is the CTA "L" train. The Blue Line operates 24 hours a day and connects the airport with downtown Chicago. The O'Hare station is located directly within Terminal 2, from where it is easy to walk to Terminals 1 and 3. The trip from the city centre (e.g., from Clark/Lake station) will take approximately 45-60 minutes. This is an ideal option to avoid traffic jams, especially during peak hours.

For those who value comfort, especially when travelling with a large amount of luggage, taxis or rideshare services like Uber and Lyft are suitable. A taxi ride from downtown Chicago to O'Hare Airport without traffic will take about 30-40 minutes, but during peak hours, the time can increase to 90 minutes or more. The cost will be significantly higher than public transport and may vary depending on demand and road conditions.

If you plan to travel by car, O'Hare Airport offers numerous parking options—from economical long-term lots to multi-level garages near the terminals. It is recommended to book a parking space online in advance to secure the best rates. Car rental counters for all major companies are located in the dedicated Multi-Modal Facility (MMF), which can be reached via the free Airport Transit System (ATS) train from any terminal.

Regional Pace buses also serve O'Hare Airport, connecting it with various suburbs. This option may be convenient if you are heading not to central Chicago, but to its outskirts. The bus station is located next to the car rental centre (MMF).

If your itinerary is more flexible, it is worth considering other airports in the region. Chicago itself has a second major airport—Midway (MDW). Also located a short distance away are General Mitchell International Airport (MKE) in Milwaukee, South Bend Airport (SBN), and Dane County Airport (MSN), which can be convenient alternatives depending on your final destination.

O'Hare International Airport (ORD) in Chicago is one of the busiest aviation hubs in the world, so understanding its structure will help you save time and reduce stress. The airport consists of four passenger terminals: 1, 2, 3, and 5. Terminals 1, 2, and 3 primarily serve domestic flights within the USA, while Terminal 5 serves as the main international terminal.

Map and Navigation:

Terminals 1, 2, and 3 are arranged in a semicircle and are connected to each other both before and after the security zone. This allows passengers with connecting flights to move between them without leaving the secure area. Terminal 5 is located separately, and to move between it and the domestic terminals, you must use the automated passenger transport system—the Airport Transit System (ATS). This free train runs around the clock, connecting all terminals, parking lots, and the car rental centre.

Terminal Features:

• Terminal 1: The main hub for United Airlines. It is famous for its underground pedestrian tunnel with the neon installation "The Sky's the Limit", connecting Concourses B and C.
• Terminal 2: Serves as a base for several airlines, including Alaska Airlines and JetBlue. It is often used for flights by partner airlines.
• Terminal 3: Is the main hub for American Airlines. Departure gates for many other carriers are also located here.
• Terminal 5: Receives and dispatches the majority of international flights. Here you will find check-in counters for foreign airlines, as well as customs and border control zones for all arriving international passengers (except those who have cleared pre-flight control in their country of departure).

Check-in and Security:

O'Hare is a massive airport, and the time required to complete procedures can be significant. It is recommended to arrive at the airport at least 2 hours before departure for a domestic flight and 3 hours before an international one. During peak hours, queues for check-in and security can be very long. Departure areas with check-in counters and security checkpoints are located on the upper level of the terminals, while arrival areas and baggage claim are on the lower level.

Navigation Tips:

Always check your terminal and gate number in advance on the airline's or airport's website. To transfer between domestic terminals (1, 2, 3), you can use the pedestrian walkways, but for travel to or from Terminal 5, allow extra time for the ATS train ride (about 10-15 minutes). Signs in the airport are clear and highly visible; follow them to easily find your boarding gate, food court, or ATS station.

The history of O'Hare International Airport (ORD) is a journey from a military plant to one of the busiest aviation hubs in the world. Its story began during World War II when a Douglas company plant, producing C-54 transport aircraft, was located on this site. After the war, in 1945, it was decided to convert the facility into a commercial airport, which was named Orchard Field. It is from this name that the airport retained its IATA code—ORD.

In 1949, the airport was renamed in honour of Lieutenant Commander Edward "Butch" O'Hare, the first US Navy ace and Medal of Honour recipient in the USA. However, full-fledged commercial air service began only in 1955. The city authorities of Chicago actively promoted the new airport, as the old Midway Airport could no longer cope with the growing flow of passengers in the post-war era. By 1962, O'Hare had taken over most of the traffic from Midway and became the busiest airport in the world—a title it held for decades.

Significant expansion phases occurred in the 1980s. It was then that the famous Terminal 1 for United Airlines was built, designed by architect Helmut Jahn. Its hallmark became the underground pedestrian tunnel connecting Concourses B and C, featuring the mesmerizing neon installation "The Sky's the Limit". In 1993, the automated passenger transport system (Airport Transit System) was launched, linking all terminals and parking areas.

In the 21st century, the massive O'Hare Modernization Program (OMP) began, aimed at reconfiguring runways to increase capacity and reduce delays. Today, O'Hare Airport remains a key hub for United Airlines and American Airlines, continuing to play a vital role in the international and domestic air transport system, serving tens of millions of passengers annually and standing as a living monument to aviation history.

O'Hare International Airport (ORD) offers passengers a full range of services and amenities to make waiting for a flight as comfortable as possible.

For those who value enhanced comfort, the airport operates airline lounges and VIP halls, available to business class passengers or for a separate fee. In these, one can relax in silence, use shower facilities, have a snack, and work.

While in Chicago, be sure to try local cuisine, and O'Hare Airport provides such an opportunity. Visit Tortas Frontera by famous chef Rick Bayless (Terminals 1, 3, 5) to enjoy Mexican sandwiches made from the freshest ingredients.

Publican Tavern (Terminal 3) offers dishes in a European bistro style, while Wicker Park Seafood & Sushi (Terminal 2) will delight lovers of fresh seafood and sushi. If you have enough time, these places allow you to take a break from the airport bustle. Most establishments open early in the morning and work until late evening, but operating hours may change, so it is recommended to check current information on the airport website.

If time is limited, numerous fast-food outlets and cafes are at your service. Here you will find both world-famous chains like Starbucks, McDonald's, and Dunkin', as well as local cafes offering sandwiches, salads, and pastries. Such establishments exist in almost every terminal, making it easy to grab a bite right at the boarding gate. The price range varies from budget options in food courts to more expensive restaurants.

O'Hare International Airport is one of the busiest aviation hubs in the world, so preparing for departure or transfer here requires special attention. To ensure your journey through the aerial gateway of Chicago goes smoothly, use these tips.

Arrival Time and Check-in. For international flights, it is recommended to arrive at the airport at least 3 hours before departure, and for domestic flights within the USA—2 hours. This will give you enough time to check in, drop off luggage, and pass security control without rushing. To save time, complete online check-in on your airline's website and save the boarding pass on your phone.

Security Control and Hand Luggage. Strict screening rules apply in American airports. All liquids in hand luggage must be in containers of no more than 100 ml (3.4 oz) and packed in a single transparent bag. Laptops and other large electronics must be removed from your bag into a separate bin. If you fly frequently, consider participating in TSA PreCheck or Global Entry programmes, which allow you to pass screening via an expedited procedure.

Tips for Seat Selection and Savings. Choose your seat on the plane in advance during online check-in: by the window for beautiful views, or by the aisle for more legroom and the ability to stand up without disturbing neighbours. To save money, take an empty reusable water bottle with you (it can be filled after security) and light snacks. The most budget-friendly way to get to downtown Chicago is the CTA "L" train (Blue Line), the station for which is located right in the airport.

For Transfer Passengers. O'Hare is a huge airport with several terminals (1, 2, 3 are domestic, 5 is international). To move between them, the automated Airport Transit System (ATS) train operates. If you arrive on an international flight and are flying further within the country, you will need to pass passport control, collect your luggage, pass customs, and then re-check it at the transfer desk. Allow at least 2-3 hours for the transfer.

Customs Control. When entering the USA from another country, all passengers undergo immigration and customs control. Be prepared to answer the officer's questions about the purpose of your trip and present the necessary documents. The process is faster for members of the Global Entry programme.

In Case of Flight Delay. If your flight is delayed, do not panic. Monitor updates via the airline's app or on departure boards. O'Hare Airport has plenty of restaurants, cafes, and shops. You can also find interesting art installations here, for example, the famous light tunnel "The Sky's the Limit", connecting Concourses B and C in Terminal 1, to brighten the wait.
