Paramedics and emergency officials surrounded Flight 985 at the Charlotte Douglas International Airport before takeoff Tuesday. The flight was headed to Montego Bay, Jamaica.
Several passengers reported being sick after complaining of an electrical smell.
Authorities say nine people complained of symptoms consistent with exposure to toxic fumes. Two pilots, five flight attendants and two passengers were taken to the hospital with non-life threatening injuries.
Other passengers were checked out as a precaution, and they will continue to Jamaica on a new plane. It's unclear what the passengers may have inhaled, but hazmat was called in and found no problems with air quality on the plane.
