PwC London Share 2016 U.S.-Booked Air Volume: $294.2 millionConsolidated Global TMC: Amex GBTThough BTN's estimate for PwC's 2016 U.S.-booked air volume is up slightly more than $3 million from 2015, that adds less than 1 percent to its U.S.-based air spend overall. That's a testament to the cost control practiced at PwC, where the U.S. employee base in fiscal year 2016 grew 8 percent and the global headcount during the same time frame grew 7 percent. It's also a testament to engagement in PwC's travel program. Program managers have reduced traveler friction and ensured productivity. The program provides traveler enrollment in TSA Precheck and in Global Entry, travel management company hours align with peak travel times and the travel program takes an omnichannel approach to accessing TMC support: telephone, online, mobile and chat. PwC has launched an internal social network to interact with travelers, which has been a game changer in answering questions as issues occur and getting candid feedback about the travel program. PwC has been a leader in traveler satisfaction by aligning with an overall corporate strategy that focuses on employee engagement and loyalty.
