When booking a flight they ask for your title, the first four are Mr (good to see men are still in their rightful place of being listed first) Mrs, Miss and Ms, are we to be offended before even writing our name on a ticket because Qantas is categorising us from the start?
Plus, and probably more an aero club bar discussion, if you flew a charter to a conference of people born with male genitalia but identified as female and booked their tickets as such. Using standard passenger weights, the aircraft could easily be a couple of ton overweight if they use all female weights rather than male weights.
