My personal opinion - the KE pants that some of the KE FAs now wear look absolutely awful. I certainly hope OZ realizes that their cabin staff are repeatedly honored with being the best in the world for reasons. Going about changing things that have worked towards putting OZ on top will likely result in disaster. If OZ's policy is that their FAs wear skirts, then the FAs need to accept that or find a job with a different airline or different job all together. Now the color of the uniform isn't the greatest, although I still prefer it over the KE uniforms.
I will admit that I've often wondered how OZ FAs manage to squat down when they want to talk to a passenger eye-to-eye. It looks horribly uncomfortable. But at the same time I greatly admire them for doing so, to handle difficult tasks with such grace. Make me to appreciate them so much more compared to their lazy counterparts on other airlines elsewhere in the world.
