X post traces O'Hare's 1960s jet-age rise

Nagyngu posted an X thread on May 25 that used archival photos and captions to trace how Chicago O’Hare became a jet-age hub in the 1960s. The post pointed to terminal construction, early route maps and traffic comparisons with the airport’s current scale, according to the thread and city records. The images line up with official Chicago histories showing O’Hare’s rapid expansion after airlines shifted service from Midway. They also revisit a period when the airport’s design and runway buildout helped position it as the city’s main long-haul gateway. ### Which 1960s milestones does the thread line up with? FlyChicago’s official O’Hare history says an eight-lane expressway link between downtown Chicago and the airport opened in 1960. The same city timeline says construction of the main terminal building and a 5,000-car parking lot concluded in 1961. In 1962, all scheduled Midway operations transferred to O’Hare, pushing passenger totals to 10 million and making it the “World’s Busiest Airport,” according to the city. (x.com) The Encyclopedia of Chicago says the terminal complex was designed as four semiautonomous buildings linked by walkways, with long “fingers” for boarding and deplaning. That layout became one of the airport’s defining visual markers in period photos and postcards from the early jet era. The same history says Mayor Richard J. Daley and President John F. Kennedy dedicated the completed facility on March 23, 1963. (flychicago.com) ### Why did O’Hare overtake Midway in that period? Chicago’s official airport history says the traffic transfer from Midway to O’Hare was complete in 1962. The city does not spell out aircraft types on that page, but the timing matches the broader jet transition that favored airports with longer runways and room to expand. By 1965, O’Hare’s passenger count had doubled to 20 million, and by 1968 it had reached 30 million, according to FlyChicago. (encyclopedia.chicagohistory.org) The city said in a 2025 anniversary release that when O’Hare opened to commercial service in October 1955, four airlines operated flights to 23 destinations. That release said the airport’s first years laid the foundation for its growth into a global hub, and noted that a dedicated international terminal opened in 1958 before the main terminal complex opened on Jan. 1, 1962.

The Encyclopedia of Chicago says planner Ralph Burke’s master plan included passenger terminals, highway access and provisions for a future rail link to downtown. After Burke’s death, C. F. Murphy Associates continued the development, and the resulting complex used linked concourses and finger piers that matched the needs of rising jet traffic. Those design choices are visible in many archival images from the period, including terminal exteriors and apron scenes with early jetliners. (chicago.gov) FlyChicago’s timeline adds that O’Hare kept expanding through the decade, opening its first taxiway bridge over a public roadway in 1967 and adding a sixth parallel runway in 1968. The city says those additions came as passenger totals climbed to 30 million. ### How does that 1960s story compare with O’Hare now? Airports Council International World said on April 14, 2026, that Chicago O’Hare led the world’s 2025 rankings for aircraft movements. (encyclopedia.chicagohistory.org) The City of Chicago said in an April 2026 release that O’Hare recorded 860,015 aircraft operations in 2025, up 10.8% from 2024. A separate city release said July 2025 was the busiest month in the airport’s history, with more than 8.26 million passengers.
