PROS have made the step from revenue management and dynamic pricing to a full offer management solution set by acquiring Vayant. PROS are by far the market leader in the provision of revenue management technology to airlines as measured by total passengers boarded. The acquisition of Vayant creates significant new opportunities for PROS to expand their footprint in their customers and challenge the PSS providers for priced availability as a cloud based service. This offering is particularly relevant today as airlines look to new ways of doing business including IATA's NDC and One Order.
