WATERLOO, ONTARIO—January 17, 2007—Descartes Systems Group announced that it has joined the International Air Transport Association's (IATA) Strategic Partner Program as an IATA e-freight 'Simplifying the Business" preferred partner.

Descartes is a global on-demand software-as-a-service logistics solutions provider. With more than 2,300 freight forwarder locations and more than 90 air carriers connected to its network, Descartes' Global Logistics Network (GLN) has supported IATA's e-freight program since its introduction in 2005.

IATA's e-freight program aims to eliminate the need to produce and transport paper documents for air cargo. Descartes' GLN solutions for airlines and freight forwarders are aligned with the critical foundations for the e-freight project, namely the IATA e-freight Message Improvement Program.

"We, like IATA, are committed to improving air cargo message quality for the collective benefit of carriers, freight forwarders, customs authorities and shippers. By supporting IATA's e-freight initiative as we enhance our own air cargo messaging services, we are taking a global approach to addressing the needs of our customers," said Edward Ryan, General Manager of Descartes' GLN. "As we work with IATA on the e-freight project, we enhance our ability to offer leading electronic freight solutions to the several thousand customers we have across the globe."

"IATA welcomes Descartes' decision to become a 'Simplifying the Business" Preferred Strategic Partner of IATA," said Mr. Patrick Murray, Systems Manager IATA e-freight. "We look forward to Descartes' participation in supporting the IATA e-freight Message Improvement Program, supporting the pilots and supporting the e-freight vision. As one of our partners, Descartes will help improve message quality, develop global standards and implement global systems for trading partners which, in turn, will lead to industry cost savings and add value to the e-freight solutions to be offered."

About IATA e-freight
In 2004, IATA launched a project, IATA e-freight, designed to eliminate the need to produce and transport paper documents for air cargo shipments by moving to a simpler, industry-wide, electronic, paper-free environment.

As IATA e-freight impacts the entire cargo supply chain, an Industry Action Group has been formed, including airlines, top freight forwarders represented by their association Freight Forward International and the World Customs Organization. Together with IATA, this group will align industry stakeholders and help drive the project forward. For more information, visit http://www.iata.org/stbsupportportal/efreight.
