Tickets at this price are valid for daily departures starting in early November through the middle of March with returns available through March 28, 2019. Iberia operates the trans-Atlantic flight and most onward connections, but on select itineraries, El Al will operate the Madrid to Tel Aviv leg of the journey. A Saturday night stay is required and peak holiday travel is blocked out.
There is scattered availability on this fare in the fall months, so you'll have the best chance to find the seats you want departing in January and February. Flights include one checked bag free of charge, per person.
As an example, I was able to find seats departing JFK on Tuesday, February 12 and returning from TLV on Thursday, February 21, 2019. Other dates are widely available during the mentioned travel window.
