Houston, Texas – September 15, 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 Low Fare Pricing Optimization, which will be hosted on Thursday, September 25, 2003, from 10 to 11 AM US Central Standard Time.

What are the main concerns facing airlines today?

• How can I compete in an environment of low fares without revenue dilution?
• How can I better categorize consumer behavior related to my fare products?

Low fares have always presented a risk of revenue dilution to airlines. With complex networks and diverse sources of commercial revenue opportunities, airlines need to correctly categorize low fare consumer behavior. PROS Revenue Management has forecasting solutions that will enable carriers to distinguish between distinct products for two distinct market segments, the traditional product with rules and restrictions, and a dynamic pricing product based solely on customers' willingness-to-pay.

PROS Revenue Management has been working over the past three years to develop the pricing, forecasting, and optimization sciences that can successfully support low fare optimization strategies. PROS believes inventory availability and pricing evaluations have to be dynamic and real-time for the constantly changing market environment. PROS has designed the architecture to provide high flexibility in implementing complex decision models and high scalability. Much of the science being proven for the low fare pricing optimization is transferred from successful revenue management science already applied in other industries such as automotive and energy.

PROS Chairman and CEO, Bert Winemiller, asserts, "All levels of the airline organization need to understand how low fare pricing optimization impacts markets. Optimization can be successfully implemented in low fare markets. PROS Revenue Management has been developing and proving our pricing science for over three years and we look forward to providing the airlines with a complete solution to compete in a continuously changing environment of low fares without revenue dilution."
