American issued the following statement regarding the flight:
"American Airlines flight 2575 from Austin–Bergstrom (AUS) to Chicago O’Hare (ORD), encountered a mechanical issue — an odor in the cabin — after takeoff. The aircraft, a Boeing 737 with 146 passengers and a crew of six, returned to AUS, landed safely and taxied to the gate. Our maintenance team is currently evaluating the aircraft.
"We apologize to our customers for the inconvenience, and are working to get them to Chicago as soon as possible."
A man whose wife was on the Chicago-bound flight tweeted that the plane's engine was cleaned the previous night, which could have been the cause of the smell.
