Yeah! When I was in the SYD airport, i was so excited to fly to HKG by an Airbus 333. I was surprised that there were 36 cabin crew who were boarding on A333. But 22 cabin crews werent working, they wore clothes whereas the others were working with their uniform. All of cabin crew wore uniforms when there were in the airport only. Maybe 22 cabin crew stayed in Sydney for one day only.
