Hm, nothing changes.
Having flown EK from the get go when based in DXB it was not unusual for some Sheikh/entourage to rock up at the check in & demand a seat/s to BAH/KWT/LHR etc etc. In those days it was just F & Y, so, people just got bumped onto the tarmac. Fortunately my employers understood the "culture" so I always went F. As we used to say, you cannot expect the mentality to change just because they went from "donkeys to Dodge & camels to Cadillac" in just 50 years. I would certainly take this up with the ACCC as the ticket was purchased from QF in Australia & was obviously "not fit for purpose". Also, do not forget the ABC Checkout programme if you get nowhere. That may make young Mr Joyce sit up & take notice, another flaw in the unholy alliance with a State run business.
