Is crew not checking bags a US-only thing?
All of my CX/SQ flights overseas the crew had checked in bags. In fact at JFK two weeks ago when I got off a CX flight from HKG there were groundstaff next to the carousel taking off every bag that had a crew tag on it.
Can confirm qantas domestic flight crews are at best strongly disincentivised to check bags and encouraged/mandated to carry on only
however. An standard trip generally would not include more than 1 overnight in a row
