7. Qantas
5/11Australia's flag carrier, Qantas fell six spots from number one due to an incident at Perth Airport in 2018, when "a combination of factors caused a 737 crew that had just exited runway 03 to taxi past stop bars and enter an active runway almost colliding with another company 737 on its take-off roll. The report into that complex and serious incident was not issued till late 2020, and too late to be included in our 2021 safety rankings," AirlineRatings.com stated.
