Houston, Texas – October 26, 2007 – PROS, a world leader in pricing and revenue optimization science and software for manufacturing, distribution, services, hotel/cruise, and airlines announced today the successful implementation of PROS Revenue Management Suite enhancements for airlines operating the new Airbus A380.

“PROS congratulates Singapore Airlines on its inaugural Airbus A380 flight from Singapore to Sydney,” stated Surain Adyanthaya, PROS Senior Vice President.  “As a long-term Singapore Airlines partner, since 1995, PROS is committed to supporting Singapore Airlines and all international airlines that plan to operate the new Airbus A380.  Of the 13 airlines with firm orders for the Airbus A380, 10 of these carriers are PROS customers. “

The typical PROS customer who is scheduled to operate the A380 has over 60% of its revenue in B2B transactions.  Airlines have the most complex and process intensive B2B pricing challenges.  They have large B2B sales forces that have pricing and negotiation autonomy for commercial contracts.  These contracts include pricing, product, and volume terms and often Most Favored Nation clauses.  In addition, airlines have multiple distribution channels that create intense channel conflict including sales agents and sales representatives with pricing power as well as OEM pricing.  Airlines have the complexities of supply constraints, significantly different supply costs, near infinite product combinations, bundled products, short product life cycles, product obsolescence, promotional pricing, and volume rebates. 

Airline B2C pricing is dominated by electronic transactions that require high-performance technology that delivers optimized prices in a 200-300 millisecond window for millions of transactions everyday.

“Airlines are the most advanced users of science-based pricing optimization, stated Bert Winemiller,” PROS Chairman and CEO.  “It is because PROS continues to provide innovative Pricing and Revenue Optimization software products to the airline industry, as well as Fortune 2000® leaders in manufacturing, distribution, and services, that PROS will remain the preferred partner for Pricing Excellence.”
