ITA E+ on TAROM ex Bucharest.
The status was recognized after I entered it on some other SkyTeam airline website because Tarom's own website does not list ITA/Alitalia as options. After entering the FFP number, I got the option to choose any seat including 1A (on all Y 738). I don't have checked bags, but I guess I could take the extra piece.
The BP reflected the status and got me into the lounge with no issues (the lounge does not otherwise take Priority Pass/LoungeKey/Dragonpass). The lounge itself is probably the worst out of carrier-operated ones I ve seen, but this is another topic.
