Yep the Avalon incident was a massive screw up.
Qantas is having so many issues lately, they have just been extremely lucky there hasn't been anything more than a serious incident. ie the 330 near Learmonth.
I agree the other carriers into Australia don't seem to have these problems and good on them. I use to be a big fan but now avoid flying Qantas. Maybe I worded the previous post incorrectly but surely Qantas has to do something to curb all the problems of late.
