What do you know about El Al? Haven't you boycotted (BDS?) them many years ago?
Ahem... Checking flight arrivals is usually done by a person that is
not on the flight.
Yes, being that I'm a TA, and I've booked hundreds of people on El Al over the years, I've checked the flight status quite a bit more often than your honor.
I stand corrected.
And thereby might be the source of my perception. In the few times when I did attempt to check LY arrival times for family members arriving, I saw huge discrepancies between reported times and what FR24 showed. You probably have many more DPs and might see it as something that doesn't happen all the time.
Though using the links you provided I did the following spot check (which I wouldn't consider egregious, but nonetheless off) should really check something close to landing.
