TWA and Qantas came a while later to the SP game in 1980/1981, and both airlines did not end up using their SP's on the dedicated routes as was originally envisaged
What routes did Qantas envisage using the SP on
rog? Did fly on their SP Sydney to Los Angeles, also flew on the Pan Am SP in the early days Los Angeles to Sydney, had to make an unexpected stop in Nandi for a splash of fuel as the winds were against us, stayed on board for the half hour it took to accomplish, told the early engines were not quite there with fuel efficiency.
