This is kind of a silly thread, as there are too many options you have to consider. If you have dates in mind, see whats available those dates. In addition to the nonstop LAX-TLV on El Al, the one stop options are: LAX-IST-TLV on Turkish, LAX-PHL-TLV on US Air/United, LAX-EWR-TLV on United, LAX-YYZ-TLV on Air Canada (All Star), LAX-TLX-TLV on Air Berlin, LAX-LHR-TLV (American/El Al) (One World).
If you're willing to stop two places, there are dozens of routings.
