After leaving school, Harrison worked at
Martins Bank from 1962 until 1964, then took a job as a
nanny for a
Swiss farmer in the
Canton of Neuchâtel in order to improve her French. She later took another job as a nanny in
San Francisco. While in San Francisco she applied for a job as a
flight attendant with
British Overseas Airways Corporation (BOAC), and she joined BOAC in May 1966. After completing her training, Harrison was assigned work on board BOAC's
Boeing 707 fleet. She moved to Emperor's Gate,
Kensington,
London, where she shared a flat with other BOAC flight attendants, and purchased a
Ford Anglia car for use in getting to work at
Heathrow Airport. She also joined Universal Aunts, which provided staff to do odd jobs; one of her assignments was babysitting
Jason Connery, son of actor
Sean Connery. While she enjoyed her job, long-haul flights with their several stopovers were exhausting, and she had told a friend she was considering quitting BOAC. On 8 April 1968 Harrison was rostered at her own request to work BOAC Flight 712 Whiskey Echo long-haul to Sydney, Australia, via Zurich, Tel Aviv, Tehran, Bombay (now Mumbai), Singapore and Perth. She told a colleague that she had been invited to a wedding in Sydney, but it is possible that she wanted to see a
Qantas pilot she had met some months before. ==Death==
