[QUOTE=ELAL;19236690]You can call the reservations office and asked to be put on the list of volunteers agreeing to be bumped.
The volunteers list applies only for overbooked flights when El Al has to ask people not to fly at all on their scheduled flight and get instead an alternative flight and a compensation.
The upgrade list is automatic and generated for every flight (although it is used only if possible, depending on flight's situation).
