Chicago O'Hare: The busy Midwestern hub of Chicago O'Hare International is set to undergo a $8.5 billion revamp. This is a rendering of the new Global Terminal.

World's busiest airport: O'Hare was for decades the busiest airport in the world. This is what the American Airlines terminal looked like in 1970.

A little... too busy: The airport became notorious for congestion and often ranked low in customer satisfaction surveys. The terminal is pictured here in 2014.

O'Hare 21: In 2019, the O'Hare 21 was unveiled, a radical plan to revamp the airport and make it ready for the 21st century.

New era: The new O'Hare Global Terminal will handle international arrivals and offer 2.2 million square feet of space, 75% more than the existing Terminal 2, which dates back to the 1950s.

Bold vision: The new terminal building will be Y shaped, with a six-pointed glass skylight positioned at the meeting of the branches. Construction won't start for several more years, until all regulatory and environmental assessments are completed.

Expansion of Terminal 5: Construction is already underway on the expansion of Terminal 5. This photo is from November 2021.

Under construction: Some areas of the new Terminal 5, which is being refurbished now, have already opened to the public.

Transition period: Delta Air Lines will relocate from Terminal 2 to the new Terminal 5 in fall 2022.
