Business Class
They did invent Business Class - it was in 1979 though. They had decided to put seats in the upper deck and someone with imagination asked around and found that either TN or AN had a surplus of DC-9 First Class seats because they'd over ordered so QF bought the lot (they were brand new), fitted them with QF seat fabric and installed them - calling it 'Business Class'.
Other airlines (such as Pan Am) claimed this but it WAS Qantas undisputedly that did this first.
A bit more of this innovative 'retro' thinking - which also led to life rafts on all aircraft world-wide, another Qantas innovation, would be welcome now days.
