I've been noticing on the CO upgrade standby list you can view online that often times two individuals with the same last name are being cleared. When I get on board I usually find it to be a couple traveling together.

This got me wondering if CO changed the way they process companion upgrades by processing both the Platinum or Gold member with the companion at the same time. It seems rather unlikely that two family members would have the same status and be upgraded together so frequently that I am noticing.
