A Spirit Airlines Airbus A320-200, registration N635NK performing flight NK-1128 (dep May 4th) from Las Vegas,NV to Tampa,FL (USA), was enroute at FL350 about 400nm west of Dallas Ft. Worth,TX (USA) when passengers complained about an unusual odour on board, a number of passengers felt sick because of the odour. The crew descended the aircraft to 10,000 feet, initially considered to divert to Albuquerque,NM (USA) but then decided to divert to Dallas Ft. Worth where the aircraft landed without further incident about 90 minutes after leaving FL350. A number of passengers were examined by paramedics awaiting the aircraft, none was taken to a hospital though.

The airline reported they are investigating the source of the odour. A replacement aircraft was to take the aircraft to Tampa.

A replacement A320-200 registration N603NK reached Tampa with a delay of 3.5 hours.
