Priceline Says Head Huston to Take on Added Duties Inc. (PCLN), the most valuable online-travel agency, said the head of its unit will take on additional duties as its international business becomes an increasingly dominant part of the company.

Darren Huston, who was named chief executive officer of in 2011, will also manage relations between Priceline’s brands, coordinate relationships with affiliates and suppliers, and handle strategic development for global expansion, the Norwalk, Connecticut-based company said today in a statement.

Huston, a former vice president at Microsoft Corp., took over after founder Kees Koolen stepped down. Since acquiring Amsterdam-based in 2005, Priceline’s annual revenue has jumped more than fivefold, based on estimates for 2012 revenue. The company’s international business accounted for 71 percent of revenue in the third quarter, up from 66 percent a year earlier.

Priceline was little changed today at $657.42 at the close in New York. The stock has climbed 37 percent in the past year.
