Bechadrei is reporting that:
LY2 is diverting to Athens, landing at 2:45 pm with shabbos starting at 4:50 pm (instead of landing in TLV a half hour before shkiah). Approx 70 frum jews on board, many who switched from LY8. El Al has secured hotel rooms, and Rabbi Hendel of Chabad Athens is getting shabbos food and a sefer torah to the hotel. (What a chessed! No easy feat!)
LY8 is diverting to Rome, landing 3:00 pm, shabbos at 4:30. It's unknown how many frum jews are on that flight, most who were originally on it switched to LY2.
