Officials say a 15-year-old Brazilian girl died on a Copa Airlines flight from Orlando to Sao Paulo after a trip to Walt Disney World.

Airport officials tell Globo TV the teen suffered a cardiac arrest a few hours before the plane was to land in Sao Paulo on Sunday.

Copa Airlines said two doctors who were passengers on the flight tried to revive the teen, but she was already dead when the plane arrived.

The Tia Augusta tourism agency that booked the girl's flight said in a statement that she had gone to an Orlando hospital with flu symptoms and tested negative for swine flu before being authorized to fly back to Brazil.
