The trend of blending business with leisure activities on business trips is on the rise, according to the second annual State of Business Travel Survey by National Car Rental. The report showed that 90 percent of millennials have engaged in “bleisure” travel in the past year, compared with 81 percent of Generation Xers and 80 percent of baby boomers. A major reason may be that they've identified a budget friendly opportunity: Nearly half (49 percent) of millennials say they've extended business travel into a leisure trip or scheduled a vacation around business travel to save on vacation costs. Despite benefits like a better work-life balance, however, millennials are leading another trend: “bleisure travel stigma.” Nearly half (45 percent) of millennials feel they should avoid telling others about taking time for fun or personal activities while on a business trip, compared with 40 percent of Gen Xers and 30 percent of baby boomers.
