Ground Facilities We lease many of the buildings and associated land that we occupy. Most of these leases are for facilities at airports with various government agencies that control the use of the airport. We lease maintenance, training and office facilities in Salt Lake City, Utah, and we lease additional maintenance facilities in Boise, Idaho; Fresno, California; Tucson, Arizona; Chicago, Illinois; Detroit, Michigan; Nashville, Tennessee; South Bend, Indiana; and Fort Wayne, Indiana.

We also own maintenance facilities on land leases with airport authorities in Milwaukee, Wisconsin; Oklahoma City, Oklahoma; and Colorado Springs, Colorado.
