CHEEKTOWAGA, N.Y. (AP) — The Federal Aviation Administration says a SkyWest Airlines flight from Chicago that made an emergency landing in Buffalo did not have a pressurization problem.

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 initial information indicated the Embraer E170 may have had a pressurization problem, but that turned out to not be correct.

SkyWest spokeswoman Marissa Snow says the plane’s oxygen masks did not release.

She says one passenger aboard the flight lost consciousness and the pilots rapidly descended “out of an abundance of caution.”

The flight was operating as United Express at the time.
