[3] Pittsburgh-Butler Regional Airport is located in Penn Township,[1] 5 miles (8 km) southwest of the central business district of Butler, the county seat of Butler County, Pennsylvania, United States.

The airport was opened by Pennsylvania Aviation Industrial Corp. (PAIC), owned by George Hann, the Mellon interests and some others, who hoped to lure Pittsburgh traffic.

In the 1930s, John Graham along with Kenny Sholter helped to clean out the hangars and reopened the airport.

[4][6] During its early years, the airport served as an important training area for potential pilots.

By the late 1990s, the airport was too small to handle the number of aircraft coming in, so plans were made to extend the runway by 800 feet (240 m).

Trump eventually held his campaign at the nearby Butler Farm Show Airport, where an attempted assassination happened.

For the 12-month period ending June 15, 2020, the airport had 74,386 aircraft operations, an average of 204 per day: 98% general aviation, 2% air taxi and <1% military.
