Marathon Oil flies to Green Bay the week of a refinery restart and Hormuz disruption

Marathon Oil flew from Jablonski Airport (33C) to Green Bay’s Austin Straubel International Airport (KGRB) on June 18, a 23-minute hop in its Gulfstream V (N540M). The flight arrived at 6:23 p.m. local time, capping a day of short legs across the Upper Midwest.

The same week, Marathon Petroleum restarted the fluid catalytic cracking unit at its Galveston Bay Refinery in Texas, per a MarketScreener report on June 16. The restart comes as the Strait of Hormuz disruption — effectively closed since early March — continues to tighten global fuel supplies, with jet fuel inventories at a six-year low in Europe’s ARA hub, according to an AInvest analysis. Marathon Petroleum’s refining margins surged 186% year-over-year in Q1 2026, per the same report, and the stock trades at roughly 7 times forward earnings despite a 60% year-to-date gain.

Marathon Oil’s recent flight history shows a pattern of short hops across the Midwest and Great Lakes region — including multiple legs to and from Chicago-area airports and Wisconsin — consistent with operational oversight of refining and pipeline assets in the region. The company, which merged with ConocoPhillips in November 2024, maintains its headquarters in Houston but keeps a visible presence in the refining corridor.
