Lights dimmed for take off and landing - agree with 100%. At least now people will have some night vision if $hit hits the fan.
Don't work for Qantas and haven't travelled with them for a while so can I assume this? The lights are on for decent while the cabin is cleared up and then off half way down the decent. Of course your eyes will only just be starting to get adjusted by the time you land but still better than on full blast as has been the case in the past.
