Qantas seems to have a PR problem...

... to match the systemic maintenance issues it denies having.  Coming one day after a cabin depressurisation on a domestic flight in Australia, and with a string (stream? torrent?) of other problems lurking fairly prominently in the collective subconscious, the average consumer now, I would suggest, has good reason to choose another airline whenever possible.  The chances of any plane falling out of the sky are miniscule, but the chances of a Qantas plane running into difficulty seem, on the basis of the past 6 months, to be much higher than average.
