A lot of airlines / crews don't have sleep facilities like CX.
I think most of the controlled rest occurs on flights with either two crew flying through their night, flights with three crew but no rest seat, flights with three crew but no lay flat rest seat.
Yeah great idea about staying on home base time. Depart HKG at 2000, arrive at destination hotel ready to get into bed at 0600 HKG time, next duty wake up is at 0200 HKG time. Wish I had thought of this brilliant idea 7 years ago
