CHEEKTOWAGA, N.Y. – Authorities say a SkyWest Airlines flight from Chicago made an emergency landing in Buffalo, New York, after three passengers lost consciousness.

The flight carrying 75 passengers departed from O’Hare International Airport and was bound for Bradley International Airport in Connecticut when it landed at Buffalo Niagara International Airport before noon Wednesday.

The FAA says the crew of the Embraer E170 reported a possible pressurization problem.

It was earlier reported that only one passenger lost consciousness, but SkyWest spokeswoman Marissa Snow said new information from medical personnel confirmed that three passengers lost consciousness. She says the passengers were evaluated and released. None were hospitalized.

Snow says maintenance personnel found no indication of a pressure problem or any other issues with the aircraft.

She says the airline is continuing to investigate.
