El Al doesn’t fly on Shabbat, from sundown Friday evening until sundown Saturday evening, as a religious observance. However they will operate from both the New York and Bangkok this Saturday to assist in bringing reservists back to Israel as part of the country’s call up of 360,000 (4% of their population).
El Al will not be charging for these flights. Instead, the cost “will be borne by El Al and large US financial institutions” according to the airline.
