[1] Elk Grove Township formerly housed the United Airlines headquarters.

In 2006 United Airlines announced that it would be moving its headquarters and its 350 top executives from Elk Grove Township to 77 West Wacker Drive in the Chicago Loop.

[5][6] After the City of Chicago gave additional financial incentives, United proceeded to schedule a move of its remaining employees out of the former Elk Grove Township headquarters into the Willis Tower (Sears Tower) in Chicago in the northern hemisphere of fall 2010.

Monica Davey of The New York Times said that the move may have contributed to United's decision to base the new merged airline out of Chicago instead of Houston.

[8][9] In December 2021, it was reported that United would sell the campus to CloudHQ, which plans to build a data center.
