The Mystery Behind O'hare Airport's Code: Unveiling The Secret

Chicago O'Hare International Airport (IATA: ORD) is one of the largest and busiest airports in the world. Located on the city's northwest side, it serves as a hub for over 50 airlines, offering non-stop flights to numerous destinations across the globe. The airport's three-letter code, ORD, has an interesting history. Originally, the airport was named Orchard Place, after a small village northwest of Chicago. During World War II, it served as an airfield for a Douglas C-54 Skymaster assembly plant. In the late 1940s, it was renamed Orchard Douglas Field, and later, O'Hare Field, in honour of World War II hero Edward Butch O'Hare. Despite the name change, the airport code ORD, derived from Orchard Douglas, remained unchanged.

O'Hare Airport's IATA code is ORD

O'Hare International Airport, located in Chicago, Illinois, is one of the largest and busiest airports in the world. The airport's IATA code is ORD. This code is a remnant of the airport's past, as it was originally named Orchard Field Airport, derived from its location in Orchard Place, a small village northwest of Chicago.

During World War II, Orchard Place served as an airfield for a Douglas C-54 Skymaster manufacturing plant. After the war, the site was renamed Orchard Douglas Field and, later, O'Hare Field in honour of World War II hero Edward "Butch" O'Hare. While the airport's name changed, its IATA code, ORD, remained the same, making it one of the few airport codes that do not directly correspond to the airport's name or location.

The IATA, or International Air Transport Association, uses these three-letter codes to identify airports worldwide. The O'Hare airport code, ORD, can be found on luggage tags, tickets, and online bookings. While the code is essential for air traffic controllers and carriers, it is also useful for travellers booking flights or trying to identify their luggage.

O'Hare International Airport is a major hub, serving Chicago alongside the smaller Midway International Airport. O'Hare offers non-stop flights to 249 destinations worldwide and is ranked as one of the busiest airports by passenger traffic. With eight runways, O'Hare handles an extensive volume of regional flights, contributing to its high ranking in airport traffic.

ORD comes from Orchard Place, a small village near Chicago

The IATA code for Chicago O'Hare International Airport is ORD. This code is derived from the name Orchard Place, a small village near Chicago. During World War II, Orchard Place served as an airfield for an assembly plant that produced Douglas C-54 Skymaster planes. The site was chosen for its easy access to the workforce and railroads of the nearby city, as well as its distance from enemy threat. The village was once home to rich farmers who enjoyed its picturesque views.

Following the war, the assembly plant ceased its operations at the airfield, and the Chicago Federal government decided to build a new airport on the site. The airport was initially named Orchard Field Airport and was assigned the IATA code ORD. This name was derived from Orchard Place and Douglas, the name of the assembly plant.

In 1949, the airport was renamed O'Hare Airport to honour Edward "Butch" O'Hare, a World War II hero and the U.S. Navy's first flying ace and Medal of Honor recipient. Despite the name change, the airport code ORD was retained, resulting in O'Hare being one of the few IATA codes that does not directly correspond to the airport's name or metropolitan area.
