SAN FRANCISCO (AP) A Dallas-bound American Airlines flight that departed from San Francisco International Airport turned around and made an emergency landing Monday at SFO after some of the cabin's wall panels came loose, aviation and airlines officials said.

The captain of the Boeing 757 decided to turn around an hour into the flight to Dallas/Fort Worth International Airport because of a possible blown air duct, American Airlines spokesman Matt Miller said.

Flight 2293 departed from SFO shortly before 1 p.m. and landed without incident at about 2:15 p.m. No one on the plane with 184 passengers and six crew members was hurt, he said.

"The captain elected to return to San Francisco and landed the plane safely," Miller said.

Even though the plane's problem is related to pressurization the cabin did not lose pressure and oxygen masks did not deploy, he said.

The FAA will work with the airline to determine the plane's problem, Federal Aviation Administration spokesman Ian Gregor said.

The passengers are still in San Francisco and American Airlines plans to send a plane from elsewhere to fly them to Dallas on Tuesday, Miller said.
