ExxonMobil Irving, Texas Share 2015 U.S.-Booked Air Volume: $185.6 millionConsolidated Global TMC: Carlson Wagonlit TravelOil and gas giant ExxonMobil sharply cut administrative expenses in 2015 amid an environment of falling oil prices that resulted in steep year-over-year declines in company’s revenue and profits. It reduced selling, general and administrative expenses—a category that includes business travel spending—by more than $1 billion from 2014 to $11.5 billion in 2015. Accordingly, BTN estimates that the company’s U.S.-booked air volume dropped considerably in 2015. Revenue dropped to $259.5 billion in 2015 from $394.1 billion the previous year, and net income fell to $16.2 billion from $32.5 billion. The company employed 73,500 people at the end of 2015, down from 75,300 one year prior.
