ORD – The Official Airport Code

History of the ORD airport code

Chicago O’Hare International Airport, one of the busiest airports in the world, is commonly referred to by its official airport code: ORD. But have you ever wondered how this abbreviation came to be? The origins of the ORD code can be traced back to the early days of aviation.

When airports were first being established, there was a need for a standardized system to identify them. In the 1930s, the International Air Transport Association (IATA) introduced a three-letter code system to identify airports around the world.

These codes were based on the phonetic pronunciation of the airport name or the city it served.

In the case of Chicago O’Hare International Airport, the original code was OR, derived from the airport’s original name, Orchard Field. However, in 1949, the airport was renamed to honor Edward “Butch” O’Hare, a World War II naval aviator and Medal of Honor recipient.

To reflect this change, the airport code was modified to ORD by simply adding the letter “D” at the end.

Since then, ORD has become synonymous with Chicago O’Hare International Airport and is recognized by travelers and aviation enthusiasts worldwide.

How airport codes are assigned

Have you ever wondered how airport codes are assigned? The process is more systematic than you might think. The International Air Transport Association (IATA) is responsible for assigning and managing airport codes globally.

When a new airport is constructed or an existing one undergoes a name change, the IATA assigns a three-letter code to represent the airport. These codes are based on a variety of factors, including the airport’s location, name, or sometimes even its previous code.

It’s important to note that airport codes are not arbitrary. They are designed to be easily recognizable and memorable for travelers. In some cases, the codes may also reflect local culture or geography.

For example, the airport code for Los Angeles International Airport is LAX, a nod to the “X” in the airport’s previous name, “Mines Field.”

If you’re curious about the airport code for a specific location, you can visit the IATA’s official website, where you’ll find a comprehensive list of airport codes from around the world.
