Related to this, I'm a FB Elite and recently when flying CZ with my parents they didn't allow all of us to check in together at the business class counter since my parents were not Elites (separate itineraries). The counter was empty and the regular check-in counter was packed. It happened first on the outbound flight from CAN to KUL so I brushed it off thinking maybe that agent was just being annoying. But, it happened again on the return CGK to CAN sector. Usually this has never been a problem, especially with CZ who've always taken care of me as a SkyTeam elite, they even used to seat me in the Premium Economy section when I purchased an economy fare ticket at no charge, happened numerous times.
