Blackstone to IPO Travelport; $2 billion targeted

NEW YORK, Dec 3 (Reuters) - Blackstone Group LP (BX.N) has filed to publicly list its travel services group Travelport on the London Stock Exchange, sources said on Monday, in an offering that could raise around $2 billion.

Blackstone bought Travelport from conglomerate Cendant Corp in August 2006 for $4.3 billion. Since the deal closed, Blackstone has cut costs and made the company profitable. UBS AG is the bank leading the London offering, sources said.

"We don't comment on rumor or speculation," Travelport spokesman Elliot Bloom said on Monday. UBS and Blackstone declined to comment. (Reporting by Michael Flaherty; Editing by Jeffrey Benkoe)
