It's like an alliance, where status with one means some transferrence of benefits to a certain degree.
"to a certain degree"
That is the key phrase. Cunard World Club (CWC) has NO transference. Very little within the other programs, although all are owned by the same parent company.
However, Celebrity and Royal Caribbean-Captain's Club and Crown and Anchor respectively, extend perks to each other's elites at the same level. Again, same parent company.
What I believe the OP was really asking-is elite status interchangeable between companies??? NO, not in the way you can ask for status match with the airlines.
