Cognos Helping Westjet Build and Utilize Robust Enterprise Analytics Environment

– Leading airline standardizing on Cognos to
gain efficiencies over financial reporting and improve
performance management decision-making –

LAS VEGAS, NV - COGNOS FORUM - June 28, 2006— Cognos (Nasdaq: COGN; TSX: CSN), the world leader in business intelligence and performance management solutions, today announced that WestJet’s (TSX: WJA) implementation of Cognos enterprise planning and business intelligence will help WestJet streamline profitability analysis and improve organizational effectiveness over financial reporting processes.

WestJet is Canada’s leading low-fare airline offering scheduled service throughout its 33-city North American network. As a rapidly growing services provider, WestJet required an end-to-end solution that would provide greater visibility and automation of certain management accounting processes for maximizing profit and quickly responding to market changes while reducing costs and improving efficiencies over financial reporting processes associated with C-SOx compliance.

With Cognos as its enterprise planning and business intelligence standard WestJet will gain:

• A better understanding of how various routes and schedules contribute to overall profitability through fine grained analysis down to the fare, flight path and other dimensions of a single airline seat.
• The ability to perform financial “what-if” analysis to support decision-making and assess the impact of utilizing different drivers and allocations of cost elements on profitability analysis.
• Standard reporting for business stakeholders and a corporate dashboard for executives to monitor key operational metrics on a daily basis.

WestJet is the overall winner of the Cognos’ “Performance Metrics Excellence” customer award presented today at Cognos Forum in Las Vegas. The company was also a finalist for the Cognos’ “Operational Excellence” and “Innovation and Best-Practices” awards. See related release at: http://www.cognos.com/news/releases/2006/0628_1.html

“Our continued growth is making profitability analysis increasingly more complex and we were beginning to exceed the capabilities of our current spreadsheet-based system,” said Hugh Dunleavy, Vice-President - Revenue WestJet. “With Cognos, we will have a familiar, spreadsheet-like environment for enterprise-level planning across our profitability processes. Our key business data will then be made available in an organized and intuitive fashion for reports which will allow for more detailed drill-down analysis. The net result will be a more efficient, timely, secure and reliable business process that has the capability to extend to other operational areas in the future.”

Enterprise planning, reporting and analysis and data management are key capabilities of the Cognos Performance Management System, which combines technology, best practices, analytical applications and solutions, and a broad network of partners into a single performance management solution for customers.

“WestJet’s application of our performance management solution is truly an innovative example of the process and performance improvements customers can gain with Cognos,” said Rich Lanahan, vice-president, Cognos Performance Management. “With greater automation and integration of its financial and operational processes, WestJet is now able to gain greater efficiencies out of recurring management processes and enjoy improved visibility and control over enterprise performance.”
