The U.S. aviation regulator decided to allow over 130 Boeing Co 777 airplanes to continue flying international trips through early 2011, despite warnings about suspect parts that have caused rare shutdowns in midair, the Wall Street Journal reported.

In July, the Federal Aviation Administration had asked Boeing to install redesigned cooling systems on some of its jets with Rolls Royce made engines by January 2011, to prevent the accumulation of ice inside the pipes of the fuel systems.
