if i recall correctly, previous round of DSC was preceded by international sales. Qantas marketing always do funny worthless promotiOns like we have seen lately post xmas, and the final nail in coffin is network wide international sale that ends on 5feb24.
my feeling is with generally slower travel demand anacdoally last xmas season, QF needs to replenish their cash coffers and the promo is due mid Feb. also work as part of cistomer first public stunt of late.
i have all flight dates and numbers ready to book. i gabe up RTW cuz cost is so high post covid
