Priester Aviation (PWA, Chicago Executive) and sibling Part 135 carriers Mayo Aviation (Denver Centennial) and Hill Private Aviation are to adopt the name of their parent entity, George J. Priester Aviation, which the current chairman and CEO says carries "historical weight."

The company began business in 1945 as a flight training school and over time expanded into aircraft management, charter, and maintenance operations. Priester Aviation operates from its Chicago Executive Airport base and specialises in the US midwest, while Mayo Aviation focuses on the Rocky Mountains and US west zone from its Aspen/Pitkin County Airport base. Priester acquired Atlanta-based Hill Private Aviation, formerly Hill Aircraft, in 2023.

"Being part of a larger George J. Priester Aviation organization allows people to immediately see the connection to a group with the nationwide resources and capabilities to serve their aviation needs anywhere,” said CEO Andy Priester.

Between them, the three subsidiaries own and manage over 80 aircraft. According to George J. Priester Aviation's website, clients have access to a range of types, including the PC-12, Nextant 400, Cessna Citation XLS, Embraer E505, Cessna Citation Sovereign, Hawker 4000, Praetor 500, Gulfstream GVII-G500, Bombardier Global 5000, Gulfstream G650, and the Bombardier Challenger 604.
