Carlson Wagonlit Travel is rolling out its Price Tracking tool worldwide, following a trial that the company claims delivered savings of up to 2 percent of total travel spend. The Price Tracking technology continually monitors prices for flights and hotel rooms, checking them against existing bookings. Whenever it identifies savings, according to the company, CWT cancels and rebooks for less, providing clients with the best possible deals – and delivering significant savings. Patrice Simon, CWT’s chief technology officer, strategy and new product development, said, “This technology can save our clients up to 2 percent – that’s a huge sum of money for any company with a sizeable travel program.”  Simon said the technology is largely automated, running in the background 24/7. The service is the result of a partnership between CWT and Yapta, a provider of airfare and hotel price-tracking services. CWT hopes to complete the global expansion over the next 18 months.
