Marathon Oil flies to Madison days after Wisconsin board meeting

Marathon Oil flew from Chippewa Valley Regional Airport in Eau Claire, Wisconsin, to Dane County Regional Truax Field in Madison on May 25, a 28-minute hop in the company's Gulfstream V (N540M). The flight arrived at 11:40 UTC.

The trip follows a pattern of recent movements that show the aircraft spending much of the prior week shuttling between Eau Claire and Madison. The previous day, May 20, the Gulfstream made at least two roundtrips between the two airports, per flight records on celebplanes.com. Marathon Oil's presence in Eau Claire coincides with the May 21 annual meeting of Marathon Petroleum Corporation's board of directors, which was held at the company's Eau Claire offices. Marathon Petroleum — not to be confused with the now-ConocoPhillips-owned Marathon Oil — is a separate refiner and pipeline operator listed on the NYSE. The aircraft, though registered to Marathon Oil before the 2024 merger with ConocoPhillips, continues to fly under legacy tail number N540M, and its recent itineraries closely track the travel needs of Marathon Petroleum executives, as disclosed in a November 2024 time-sharing agreement filed with the SEC that lists the aircraft at a Findlay, Ohio base, suggesting the jet now serves the post-merger corporate fleet.
