Particularly while BA are not overnighting crews, I understand the quick turn of the aircraft in TLV. Once they begin overnighting the crews, however, I hope the second outbound is retimed to something a bit earlier with the aircraft staying on the ground for a few more hours. (Both AMM and CAI leave LHR around 15:00, arrive later in the evening, and turn around first thing the following morning - something most passengers would likely prefer).
The 9pm LHR departure is brutal, and the opportunity cost of an A321 sitting a few more hours is presumably lower than a long-haul aircraft.
