I guess the logistics and realities of a truly unified loyalty program make it unlikely to happen.
I made Elite status because Royal Caribbean will give you equivalent status across their lines. I was second to the top on Royal Caribbean and then with the additional Celebrity and Azamara cruises it put me at Elite level. I'll have to check to see if Azamara cruise still add to your Captain's Club points or if they have eliminated that. If anyone knows please post it.
