Houston, Texas – October 29, 2003 —PROS Revenue Management, a world leader in pricing and revenue optimization science and software, and the pioneer and dominant provider of revenue optimization to the travel & transportation industry, invites you to attend a web seminar spotlighting PROS Group Revenue Management System (PROS Group) which will be hosted on Wednesday, November 12, 2003, at 10:00 am US Central Time. This seminar is for airline CEOs and CFOs.

What are the main concerns facing airline executives today?

• How can I improve my Group yields while maintaining market share and customer relationships?

• How can I ensure that Group Acceptance procedures are based on statistical decision support?

• How can I get both the Sales and RM departments to work together in the Group Sales environment?

PROS provides the airline industry with the state-of-the-art, proven solution for airline group revenue management. PROS Group allows an airline to evaluate a group request with the efficiency to respond within minutes. Based on specific economic calculations, PROS Group can assess the displacement cost of accepting a group at the time of the request versus waiting for individual paying passengers who are forecast to come, in the context of the historical data, thereby generating the optimal revenue mix for the flight. Both one-time travel groups and series group travelers can be evaluated using this system. There are more PROS Group Revenue Management Systems installed and operational than any other group revenue management system in the airline industry.

The Web format for the seminar will allow participants to attend from remote locations, ask questions in real-time, and interact with the presenter through an Internet browser and toll-free telephone number. This seminar is free of charge but space is limited. For more information and registration, please check PROS’ Web site at the following link: www.prosrm.com.
