CHICAGO (Reuters) - An American Airlines flight made an emergency landing and was evacuated in Los Angeles on Tuesday after smoke was detected in the cabin.

There were no injuries among the 188 passengers and six crew members on the Boeing 757, said Tim Smith, spokesman for AMR Corp, American’s parent company.

Flight 31 from Los Angeles to Honolulu departed at 8:48 a.m. PDT (11:48 a.m. EDT) and returned because of “smoke or haze” in the cabin, Smith said. He noted that there was no sign of fire.

The plane was evacuated using the four slides that are packed into the doors of the aircraft. Smith said he did not know why the slides were used in this evacuation, adding the procedure is “fairly uncommon.”

The landing was normal, and passengers were bussed to the terminal. Smith said it was unclear what had caused the smoke in the cabin. He said the plane, made by Boeing Co, would be taken out of service for an investigation.
