Qantas operates flightseeing charters to Antarctica on behalf of Croydon Travel. It first flew Antarctic flightseeing trips in 1977. They were suspended for a number of years due to the crash of Air New Zealand Flight 901 on Mount Erebus in 1979. Qantas restarted the flights in 1994. Although these flights do not touch down, they require specific polar operations and crew training due to factors like sector whiteout, which contributed to the 1979 Air New Zealand disaster.
