When flying from Ben-Gurion airport to the destinations at the territory of the Russian Federation you can check in for your flight with EL AL and check your baggage through to your final destination provided that you do not have any goods subject to a written declaration in your baggage.
In all other cases, you should pick up your baggage at Domodedovo Airport and go through customs (regardless of whether your baggage is checked through to the final destination or just to Moscow). Then you should drop your baggage at the check-in counter.
Attention! Through baggage check-in does not exempt a passenger from liability for the presence of goods in the baggage that are subject to customs declaration, or banned for import/export in accordance with the legislation of the Customs Union and customs legislation of the Russian Federation, and are discovered during customs clearance at the transfer point. If you are unable to fulfill all the conditions and requirements for transit baggage, your baggage will be checked to the first transfer point.
