Deleting using LEFT JOIN

Question

I want to delete from a table depending on data that exists on another table that references the first, however, I have the code that works and shows the value to be deleted when I run it as a SELECT stetement, however when I change that to DELETE it gives me errors, that I don't understand why they're there.

DELETE leadCustomer.* FROM coursework.leadCustomer LEFT JOIN coursework.flightBooking
ON leadCustomer.customerID = flightBooking.customerID
WHERE leadCustomer.customerID NOT IN (
SELECT customerID FROM (SELECT customerID, status FROM coursework.flightBooking) AS
StatusCount where status IN  ('R','H') GROUP BY customerID
)
AND leadCustomer.customerID = 8;

Error:

ERROR:  syntax error at or near "leadCustomer"
LINE 1: DELETE leadCustomer.* FROM coursework.leadCustomer LEFT JOIN...
               ^

********** Error **********

ERROR: syntax error at or near "leadCustomer"
SQL state: 42601
Character: 8

I am using postgres

DELETE A FROM ARTICULO_ALMACEN A

AND A.COD_ALMACEN = H.COD_ARTICULO_ALMACEN
AND A.TPROPIEDAD1 = H.PROPIEDAD1
AND A.TPROPIEDAD2 = H.PROPIEDAD2
AND A.TPROPIEDAD3 = H.PROPIEDAD3
WHERE H.COD_ARTICULO IS NULL
