I also hear Ansett employees (well, CC anyways) got 12 free flights domestically a year at one stage.
It was Ansett Domestic cabin crew. Qantas Short Haul cabin crew get the same thing. It's 12 free trips, by the way. Not 12 free flights. The onload category is very low so you have go to be careful when using them. It is a great perk, which is surprisingly underused.
As far as I am aware Ansett and Australian Airlines, later Qantas SH, cabin crew were on similar money and conditions. For many years Qantas SH cabin crew had Band payments and Ansett cabin crew did not. Bands are payments for working unsociable hours. Juniors at Ansett got stuck working weekends and early duties for year and years. At Qantas it is less likely to happen as Bands meant people chased the extra money. (There is the term 'Band Mole', LOL. I am not one of them - give me weekends off, thanks!)
