The AMR Corporation, the parent of American Airlines, said Tuesday it would immediately stop displaying and selling tickets through Orbitz Worldwide after winning court permission to pull its listings from the online travel site.

Tuesday’s decision by an Illinois state court in Chicago lifted a temporary restraining order granted last month that prevented American from dropping Orbitz, according to the airline.

American, based in Fort Worth, Tex., has developed a system of its own called Direct Connect that provides fare pricing and options directly to larger online travel agencies. The carrier also is trying to drive more bookings through its own website at AA.com.

“In today’s competitive marketplace, it is important for American to be free to customize its product offerings to improve the customer experience, as well as distribute its products in a way that does not result in unnecessary costs,” Ryan Mikolasik, a spokesman for American Airlines, said in a statement.
