Hi guys!
Just curious what membership tiers garners the FA's / ISM's personal greeting on board CX, and since everybody's on this forum it should be quite easy to collate this info!
Obviously you'd have to have your CX/OW no. on your boarding pass, for the tier to show in their system.

CX DM / GO / SL?
OW Emerald / Sapphire / Ruby?

Does it matter if you're seated in Y, PY or J? (given everybody in F are royalty anyways)
