Occidental Petroleum returns to Houston as Vicki Hollub prepares to retire

Occidental Petroleum flew from Glasgow to Houston on May 17, 2026, arriving at George Bush Intercontinental aboard its Gulfstream G650ER (tail N650XY) after an 8-hour 35-minute crossing. The trip followed the aircraft's move from Houston to Scotland a day earlier.

The flight lands the same week Occidental Petroleum's chief executive, Vicki Hollub, is preparing to retire effective June 1 after a decade at the helm, as announced on May 1 and confirmed during the company's first-quarter earnings call on May 6 [bloomberglaw.com]. Per that call, which was covered by Yahoo Finance, the company said it had already exceeded guidance in key segments and that COO Richard Jackson would succeed Hollub [finance.yahoo.com]. Hollub's retirement was widely reported by Reuters and others as marking the end of a rare female chief's tenure in U.S. oil [cnbc.com].

The Gulfstream is one of three aircraft in Occidental Petroleum's fleet, often used for executive travel between Houston and field operations in the Permian Basin or visits to Berkshire Hathaway in Omaha. This Glasgow stopover likely concludes a European leg; the company operates in the Middle East and North Africa, and Hollub has been active in succession planning and strategic transitions.
