INDIANAPOLIS (AP) — The Federal Aviation Administration says a United Airlines flight was diverted to Indianapolis because of a pressurization problem.

FAA spokesman Lynn Lunsford says the flight aboard an Embraer E145 headed from Charlotte, North Carolina, to Chicago's O'Hare International Airport was diverted to Indianapolis International Airport on Sunday morning.

He says the FAA will follow up with the airport to determine the cause of the pressurization problem.
