Let's try to explain how scheduling works for some who seem a bit confused.
We have 2 aircrafts:
Aircraft 1:
Departs to Newark Motzei Shabbos and arrives at 5:40am
Departs Newark at 1:30pm and arrives in TLV at 7:10am Monday morning.
It then departs at 10:15am to LHR, and leaves LHR at 3:25pm arriving in TLV about 10:15pm on Monday evening.
It then sets out to EWR again at 12:30am to arrive in EWR Tuesday morning at 5:50am
And so on....
Aircraft 2:
Departs TLV to LHR on Sunday at 10:15am and is back in TLV at 10:15pm so that it can head out to Newark for the Sunday night 12:30am flight, because the aircraft that flew to Newark Motzei Shabbos still hasn't returned and will only be arriving in TLV at 7:10am the following morning.
Then arrives back in TLV early Tuesday morning and does the Tuesday route to London, since the aircraft that did it Monday is now enroute to EWR
And so on.....
