Officials say a flight attendant who has a pilot's license helped land a plane at Chicago's O'Hare International Airport when a co-pilot became ill.
American Airlines spokeswoman Mary Frances Fagan says the co-pilot of a flight from San Francisco to Chicago on Monday became ill.
Fagan says the flight's pilot then checked if any off-duty airline pilots were on board. A flight attendant told the captain that she is a commercial pilot and he asked her to fill in as a first officer.
The plane landed safely.
Officials say the first officer's condition was not serious. He was treated at a local hospital and released.
