Delta Airlines and United Airlines have signed a new content agreement with Sabre Travel Network allowing Delta's and United's published fares and inventory to be available to users of Sabre's computerized travel reservation system.

The seven-year deal with Delta also includes published fares that Delta sells through any third-party distributor, its reservation offices and Web site.

Delta also signed a new marketing agreement with Travelocity, a subsidiary of Southlake-based Sabre Holdings, an online travel Web site.

United signed a five-year deal with Sabre and Travelocity.

Financial terms of the deals were not disclosed.

"This agreement further supports Delta's restructuring efforts, including our goal to effectively manage our distribution costs," said Lee Macenczak, Delta's executive vice president of sales and customer service. "We are committed to providing multiple distribution options that are both preferred by our customers and offer attractive economics to Delta."
