Marathon Oil jet touches down in Madison as executive travel pattern persists.

Marathon Oil’s Gulfstream V (N540M) flew from Aurora Municipal Airport in Illinois to Dane County Regional Truax Field in Madison, Wisconsin, on the evening of May 25, 2026, a flight of just 33 minutes.

The short hop is the latest leg in a busy stretch of Midwest travel this week. Marathon Oil has formal time-sharing agreements with senior executives of its parent company, Marathon Petroleum Corporation — including Chief Executive Officer Maryann T. Mannen — that allow them to use company aircraft for personal travel on an as-needed basis, per SEC filings. Madison is not listed among Marathon Oil’s recurring business destinations (typically Houston, Oklahoma City, Minneapolis, Washington D.C., Austin, Chicago, and Dubai), suggesting this flight was personal.

N540M has been crisscrossing Wisconsin, Illinois, Indiana, and Ohio since May 21, hitting Chippewa Valley, Dane County, Quad Cities, and Aurora in a series of short hops. An aircraft time-sharing agreement filed with the SEC, covering a fleet that includes a Gulfstream V, notes that the pilot in command retains final authority to cancel or divert any flight for safety; no such issues arose here. The pattern points to a private trip rather than a board meeting or investor event.
