When the plane landed in Montana, paramedics boarded the aircraft and pronounced the woman dead at the scene. Billings airport supervisor Mike Glancy told the Billings Gazette that he did not know if the woman died during the flight or after it landed.

Once safely on the ground, the remaining passengers deplaned, and the aircraft was inspected and refueled by mechanics. After being cleared by airport personnel, the passengers were then allowed to re-enter the plane, and it departed for its destination in San Francisco at around midnight.

The plane landed safely in San Francisco at about 1:20 a.m. local time.
