El Al closed their call centers when they suspended service last March.
For a while it was nearly impossible to reach them, but they reopened the ability to chat with them over Whatsapp at +972-3-977-1111, though with long wait times.
They have now reopened their Israeli call center, at the same number as above, though with limited hours. They are open Sunday-Thursday from 8am-5pm local time (1am-10am EDT), Friday from 8am-1pm local time (1am-6am EDT), and Saturdays evenings until midnight local time. Hopefully they will restore 24 hour service as their operations return to normal.
You can talk to the Israeli call center in English or Hebrew.
El Al’s US call center is still closed, though people have long said that it was well worth paying Google Voice the 1 cent a minute long distance rate for the far superior customer service offered by the Israeli call center.
