Narrative:

As we were nearing the end of boarding the csa came and asked if we'd allow a commuting flight attendant to sit in X6. As [flight attendant] a I stated I didn't believe we could do that as we're not allowed to sit on the jumpseat seat together. Csa stated it was 'up to us' actually said it was 'up to the D flight attendant.' I couldn't find anything regarding that in my efb and the D flight attendant said she didn't care. So we took the csa at her word and went with the commuter sitting in X6.upon arriving into ZZZ this morning I asked a supervisor and she stated no; no one is allowed by FAA to sit in X6 if there is a D flight attendant in X4.if questions arise with new 'covid' jumpseat or any other procedures I don't feel is correct. Take the time to contact a supervisor to get the correct answer.
