Orbitz.com, the flagship brand of Orbitz Worldwide in the United States, and its affiliated online travel brand ebookers.com in the United Kingdom, announced that they have signed a multi-year deal with Microsoft

to serve as the online travel agency for MSN.com's travel portal in the United States (http://travel.msn.com) and United Kingdom (http://travel.uk.msn.com), respectively.

Orbitz.com and ebookers.com will power all of MSN Travel's offerings, including air, hotel, vacation package, cruise and car rental bookings.

Following the July 1st launch, MSN Travel customers in the United States will benefit from Orbitz.com's unique new "Price Assurance(SM)" service, which refunds the difference in airfare for travelers in the event another Orbitz customer books the same flight itinerary for a lower price. MSN customers in the United States will also benefit from OrbitzTLC, an innovative service that proactively alerts customers with information about their trip via email, phone or text message.

MSN Travel customers in the UK will benefit from ebookers.com's Price Guarantee, which refunds the difference if the customer finds a better price. MSN users in the United Kingdom will also benefit from a fantastic range of worldwide hotels with up to 60% off.

Microsoft also plans to integrate more content from its newly-acquired Live Search Farecast travel search engine within the MSN Travel site as well.

"Our partnership with MSN will provide additional visibility and traffic to both Orbitz.com and ebookers.com, strengthening growth in both the United States and the United Kingdom," said Steve Barnhart, CEO and president of Orbitz Worldwide. "As one of the largest Internet destinations in the world, MSN represents another significant win for growing our co-branded distribution."

Orbitz Worldwide's co-branded and private label business powers travel bookings for a number of airline, hotel and general interest websites.
