IHS Global Insight has released new research on the link between business travel and profits. The study, commissioned by the National Business Travel Association and American Express Business Travel, used government data spanning 10 years (1998–2008), across 15 industries and 9,500 U.S. companies. Among the key findings: An incremental 1 percent increase or decrease in travel spend yielded a 1.7 percent increase or decrease in sales. Further, based on 2008 data, corporate profits would be maximized if business travel were increased by 5.3 percent, or about $14 billion. NBTA members and subscribers to American Express eXpert insights will receive access to the full report when it becomes available.
