Stop on the way to Israel: a few days, often a Shabbos, in one of more than 50 cities, for less than flying straight through.
Two tickets, a few days in a city on the way, often a Shabbos there, and often less than flying straight through. 90 cities, from London and Rome to Tbilisi, Tashkent, Marrakesh and the Vilna Gaon’s Vilnius. Every flight is checked against Shabbos and Yom Tov in both cities. Build any stopover yourself on Kiwi.com.
Separate tickets: if the first flight is late, the second airline will not wait, and bags do not go through, so leave a full day and take travel insurance. Fares are found by Travelpayouts and change quickly; the airline’s page has the final word. Times are local.
