I called Alaska asking about this a few times and it seems like they were going to try to do this before Covid, but has since been put on the back burner. I have some family members that were able to purchase connecting flights on Alaska through el al, TLV to LAX El Al, connecting to Alaska LAX-SJC, Which means there is codeshares at least one way call my I hope at some point there is a codeshare the other way.
