That's not 100% certain. You could claim that there was no other option for you to choose from at the time so you took it, even though the times are highly inconvenient, and mean a wasted day on arrival at TLV, but that now they are allowing rebooking with ELAL things look different. I did that for two different bookings (both Avios, btw) with two separate agents, and it worked. If it fails the first time, HUCA.
