IBM Armonk, NY Share 2016 U.S.-Booked Air Volume: $465 millionPrincipal Air Suppliers: American, DeltaPrincipal Hotel Suppliers: Hilton, MarriottPrincipal Car Rental Suppliers: Avis, HertzPrincipal Online Booking Tool: ConcurPrincipal Card Supplier: American ExpressPrincipal Expense Supplier: ConcurConsolidated Global TMC: Amex GBTBTN estimates that IBM's U.S.-booked air volume decreased by $25 million in 2016, even as the number of tickets it issued increased by 1 percent. In doing so, the technology and consulting heavyweight, with $2 billion in global T&E last year, slipped from its position as the largest corporate buyer of U.S.-booked air travel for the first time in the 30 years that BTN has ranked the top 100.In 2016, IBM signed a global deal to combine T&E under Concur. IBM's use of the Orbitz for Business tool came to a complete stop on Dec. 1, and by year-end, IBM had rolled out Concur in 33 countries. The company launched Concur Travel & Expense in the U.S. in May 2017. By January 2018, it plans to roll out Concur Travel to all 99 countries where it manages travel and Concur Expense to all 112 countries where it has offices. IBM also introduced an internal social network, Travel@IBM. This year, the travel program and the company's research division delivered an intelligence tool called IBM Travel Manager to help travel teams manage contracts and traveler expenses at the business unit level. It has rolled out to business managers internally and soon will be used by IBM customers, as well.In 2016, the company conducted internal surveys and interviews, talked with corporate peers and worked with Concur and the IBM global client group to create a policy survey that it is using to benchmark and establish policy parameters. The company is now focusing on how to improve the traveler experience for little or no cost. The travel team also worked with American Express and American Express Global Business Travel to improve its strategic approach as it renewed its card and travel agreements last year. IBM's security, HR and travel procurement teams work with American Express GBT on duty of care. Travelers also have mobile access to International SOS, iJet or the TMC.The primary focus of the travel team now is to develop and implement a mobile program by the end of the year. Working with the same research division resources that went into IBM Travel Manager, the travel team plans to pilot a mobile app in the fourth quarter.
