Seem to be a lot of "errors" happening lately by some big companies, a large hardware chain published a list of almost 30 items in their latest catalog that were unavailable, not so long ago a large supermarket advertised two cartons of beer for the single carton price etc etc.
This is not just one price error, its multiple errors on different pages if you count each city as a page, surely the price for such an error by a large well known company such as Qantas should be more than an "oop's, we are sorry", what happened to responsibility for your actions?
To be frank I am a little bit tired of specials that sell out in minutes, or were items that were never specials because of an error, I am sure there are quite a few unemployed marketing/sales professionals that could have done a lot better job than this!
