Ive done it with WN with no issue. I don't know if El Al has any special security concerns though.
At the ticket counter I need my ID, the passenger's name, and the passenger's PNR. It's really been hassle free. Note that they will only issue a gate pass to one person, so if you have more non-travelers coming to the airport they will have to wait outside security.
Give El Al a call to confirm. In the US: 800-223-6700
