Worldspan has resolved a recent service level contract dispute with Chicago-based Orbitz, another online travel service company that it threatened to sue at one time.

The companies say they now have reached a resolution that solidifies the importance of their travel technology partnership and allows for the continued growth and advancement of both companies.

“Worldspan has clearly demonstrated the superior service and support required to exceed the needs of our customers,” said Rakesh Gangwal, chairman, president and chief executive officer for Worldspan. “We greatly value our relationship with Orbitz and look forward to a long-term productive relationship.”

Atlanta-based Worldspan, formerly owned by Delta, American and Northwest airlines, provides behind-the-scenes booking processing for customers, including airlines, Web sites and travel agencies. Orbitz is a major client.

“Worldspan has been and continues to be an outstanding service provider,” said Jeff Katz, chairman, president and CEO of Orbitz. “We are pleased that our dispute is now resolved and we look forward to maintaining our successful technology partnership with Worldspan as Orbitz continues to grow its business in online travel.”
