The Qantas website is pretty clear.

Why is it when someone does not read something properly before booking, often their reaction is along the lines of "it should be flashing in clear font". Not sure many people would like a website where every piece of important information flashes at you.
To be fair, if he bought the ticket from QF, and when doing so QF positively told him in relation to his specific booking that he would get 2 x 23 kg when the truth is that he will only get 20 kg, that does seem to me to contain the seeds of a legitimate complaint.
I can also understand a degree of frustration about that, even if I can't sympathise with the degree of fury worked up over $24 to increase the allowance to 40 kg which is within striking distance of 2 x 23 kg.
But I agree that if there is no specific representation about the baggage allowance for a particular booking, and the passenger can find the information pretty quickly on the QF website, then it would be dreadful to require the baggage allowance to be "FLASHING in big font". We'd need to have the departure time "FLASHING in big font" as well; and the check-in deadlines "FLASHING in big font". Likewise, the whole section on security requirements would surely have to be "FLASHING in big font" - but there is so much in that section that QF might perhaps be able to stagger the flashing, and perhaps add "Stayin' Alive" as the backing soundtrack to accompany it.
