An American Airlines plane made an emergency landing at Orlando International Airport after smoke appeared in the cabin, officials said.
No injuries were reported, and there was no fire.
The Boeing 757 was carrying 187 passengers and six crew members on a flight from Fort Lauderdale to Los Angeles.
Passengers smelled smoke about 20 minutes into the flight. The plane landed in Orlando shortly after noon, said Kathleen Bergen, a Federal Aviation Administration spokeswoman.
A replacement plane was brought in to take the passengers to Los Angeles.
