Left Luggage Behind at JFK AA Greenwich 2 weeks ago. Who can i contact?

Lost Carryon Luggage at AA Greenwich Lounge on a JL3 late night flight departing 1:40am on 10/24. Is there a contact number for the AA Greenwich Lounge? Upon returning from trip last night we went to lost and found outside arrivals JFK T8 and they didn’t have the luggage even though we saw the airtag nearby.
