Chicago officials say there were no injuries after an emergency landing at O'Hare International Airport.
Chicago Department of Aviation spokeswoman Karen Pride says there was "a pressurization problem" on the American Airlines flight 2363, which landed around 10:30 a.m. Sunday.
According to American Airlines' Web site, flight 2363 was headed from O'Hare to the Yampa Valley Regional Airport in Colorado. It arrived after 1 p.m. — about two hours later than scheduled.
Chicago Fire Department spokesman Larry Langford says there were 119 people aboard the Boeing 737.
An American Airlines spokesman didn't immediately respond to a request for comment.
