O'Hare.

Introduction

Chicago O’Hare International Airport (ORD) is much more than a transit hub—it's a historic gateway connecting Chicago to the world. As one of the busiest airports globally, O’Hare boasts a fascinating transformation from a World War II military airfield to a state-of-the-art international gateway. This guide provides a comprehensive overview of O’Hare’s history, operational details, terminal layouts, transportation, amenities, visiting hours, ticketing, travel tips, and nearby Chicago attractions. Whether you're a seasoned traveler, a first-time visitor, or an aviation enthusiast, this article equips you with everything you need to navigate O’Hare and explore the best of Chicago.

Early Origins and Military Foundations

O’Hare’s beginnings trace back to World War II when the U.S. Army Air Corps acquired farmland in the Orchard Place area for the Douglas Aircraft Company’s C-54 Skymaster production plant. This facility produced hundreds of aircraft vital for the war effort, transforming the site into a crucial military logistics hub (From the Travel Desk; HistoryCentral). Post-war, Chicago purchased the land to relieve congestion at Midway Airport, laying the foundation for O’Hare’s future.

Transition to Civil Aviation and Naming

Initially known as Orchard Field Airport (hence the “ORD” code), the site was renamed in 1949 to honor Lieutenant Commander Edward “Butch” O’Hare, a World War II Medal of Honor recipient. The renaming reflected both Chicago’s aviation ambitions and its recognition of military heroism (Simple Flying; TravelAsker; Wikipedia).

Innovative Airport Design and Growth

O’Hare was among the first U.S. airports to implement a master-planned layout, featuring radial concourses, jet bridges (introduced in 1958), underground fueling, and integrated highway and rail links (Simple Flying). Passenger service began in 1955, and the opening of the Kennedy Expressway in 1960 fueled rapid growth. By 1961, O’Hare was the U.S.’s second-busiest airport (From the Travel Desk).

The Jet Age and O'Hare's Rise as a Global Hub

The advent of jet airliners in the late 1950s and early 1960s, including the Boeing 707 and Douglas DC-8, shifted Chicago’s aviation focus to O’Hare. Midway’s runways were too short for jets, prompting airlines to consolidate operations at O’Hare. In 1959, American Airlines launched O’Hare’s first scheduled jet service (Simple Flying). By 1963, O’Hare had become the world’s busiest airport, a title it held for 35 years (Wikipedia).

Expansion, Modernization, and Challenges

The 1970s-80s saw O’Hare expand with new runways and terminals, but intersecting runway layouts caused increasing delays as traffic soared (Wikipedia). Deregulation in 1978 accelerated growth, with United and American establishing major hubs. By the 1990s, congestion and delays prompted the O’Hare Modernization Plan (OMP), launched in 2001 to reconfigure runways and expand terminals (Wikipedia).

O’Hare in the 21st Century

Today, O’Hare remains a global powerhouse. In 2023, it handled over 73.8 million passengers and more than 919,000 aircraft movements, ranking #1 globally for flights (Airport-O’Hare.com; Wikipedia). As a hub for American and United, and a base for low-cost airlines, O’Hare connects Chicago to over 214 destinations worldwide (Simple Flying). Its four terminals offer extensive amenities, and recent TSA records show continued growth in passenger volumes (Union Rayo).
