There aren't enough hours in the day for 1 330 to do 2 rotations to TLV.
I beleive it will start around early April, but thats just a best guess.
If it leaves around 2200z 'twould arrive ~0300z which is 0500local. The return assuming again about 5 hrs+1.5 hrs turnaround would put it back into LHR about 0930z. Even with a reduced report of 60 mins thats 12h30 which is over max FDP for pilots, and 30 mins inside for CC (but they usually have a longer report anyway, 75 mins).
I don't see it being a there and back, looks more like a ~27 hr layover.
