During the disaster on the plane, the window side was destroyed, causing the passengers sucked out of the plane. After Dustin and a passenger being fell out of the plane, Christa tries to hold onto the hand of Ms. Lewton, and is even heard saying, "Mrs. Lewton! Help!". But it was too late and Christa is sucked out of the plane, dying instantly.
She heard Alex shouting about her premonition. But she did not believe him, and she remained on it when it took off. It can be assured that Christa died as the same way as what happened in Alex's premonition.
