From El Al's Facebook page:

IMPORTANT SECURITY CHANGE AT JFK TERMINAL 4: TSA security will be conveniently located on the same floor as all check-in counters. Plus, EL AL First and Platinum Business Class passengers will go through this TSA security checkpoint before entering the King David Lounges. With this new security location, EL AL premium class passengers can relax and await their flight departure in comfort in the lounge for a longer period of time.
(For the next few weeks, due to construction, TSA will not have separate security lines for First and Business Class passengers travelling on any airline. We apologize for the inconvenience but this is a TSA arrangement.)
Thank you.
