Iberia Airlines Iberia Plus - Iberia Biz from JFK

Hi i am flying in Biz with Iberia from JFK. Have never used them before. Can someone tell me which door at JFK terminal I should go through, Is it the last set of doors where BA and CX biz and first check in? I know it sounds petty, but I am traveling with 2 elderly people and want to avoid having them walk extra.

All the Oneworld airlines in T7 use the BA premium F/J check-in area, which is to the left as you face the terminal. It also has a separate security check which is generally much faster. I would presume IB uses this too, I know QF and CX do, along with BA. But in any case this is a really small terminal (maybe the smallest at JFK), so the distances are not great from the central area to the priority check-in.
