Experienced a second time today that not all SkyTeam lounge personnel are familiar with Diamond status.

Here at Alitalia's MXP lounge, the lady at the door intended to turn me away because I was neither Platinum Elite nor SkyTeam Elite Plus. Polite persistence swayed her to look on another screen than the standard AZ one. There she found the listing for DM.

Glad entry was successful because the flight to FCO is delayed nearly an hout.
