A Frontier Airlines Airbus A321-200, registration N717FR from Denver,CO to Raleigh/Durham,NC (USA) with 160 people on board, was climbing out of Denver's runway 25 when the crew stopped the climb at 11,000 feet reporting an odour indicating they had some sort of contamination on board. The aircraft returned to Denver for a safe landing on runway 26 about 30 minutes after departure.

Denver Airport reported the aircraft returned for "medical reasons" subsequently changing to "mechanical reasons".

The airline reported: "Shortly following takeoff from Denver International Airport, Flight 560 bound for Raleigh-Durham with 160 passengers on board, experienced a fume event which prompted the flight crew to return the aircraft to Denver and request support from emergency medical personnel as a matter of precaution. A number of passengers and the flight crew were seen by EMS professionals at the gate. No reports of individuals requiring further medical treatment have been received."
