Nearly 70 percent of travel buyers say their travelers have been affected by a payment-related data breach from an outside vendor such as an airline, hotel or retailer in the past year, according to research from the Global Business Travel Association (GBTA), in partnership with AirPlus International, a payment solution provider. The survey of 144 US travel buyers also revealed that they believe the risk of fraud is growing, with two-thirds (68 percent) saying travel programs face a greater threat today than they did two or three years ago. According to the GBTA, nearly half of all travel departments are engaged with various payment security functions. Most are involved in responding to payment fraud by an external party, educating travelers about payment security and setting policies related to fraud prevention. The survey revealed that involvement does not vary much by travel spend or program reach (such as national versus global).
