Yes, I agree, however most are more likely to fly more often then cruise. So, it might be more reasonable to "meet the standard" for flying. Because of B2Bs, we cruise more often then we fly. I'd be fine with perhaps a 5 year sunset on some part of one's cruise loyalty status. Heck, we are Elite plus (2,000 + pts) on Celebrity and haven't sailed on them for 7 years.
