Personally, I see this as a non-story ... it appears to be based on one passenger being bumped.
The real story appears - superficially - to be a lack of training on the new system for check-in staff. This should come as no surprise to anyone who had to explain the new PYOB BPs with bar-code to gate-staff when they were first introduced.
HOWEVER lines like "The system is the latest problem for Qantas in what has been a dire month." are appearing all too commonly of late. If this continues - and it does appear as though the Flying Roo is in the sights of the Australian Media at present - then it must start to have an effect on the general public perception of the company.
