Yup, some flights are going to be extremely unlikely to change and are basically always 100% booked. QF10 London-Perth (Boeing 787-9 Dreamliner) will not be affected at all by a non-trivial percentage of people refusing to fly it. There's not enough supply on those routes and Qantas can fly whatever they want there.
