Qantas's livery may be old but i think it is simple, nice and it represents Australia for it's kangaroo. Maybe they can improve on it but the main idea of this stays? But i think they need to was their aircrafts though.
my 2c worth.
By the way, a lot of people here know it is an Australian carrier coz it has that thingie that can hop on the tail!
and they cant recognise others.
