Yes, DL not codesharing with SV is pretty well known around here. However, you made some other rather far-fetched claims ("Saudi wanted Delta to discriminate Jews on all Delta flights including US domestic flights." topping my list.) that you have not provided evidence for. Of course, it's not possible to provide evidence to support such a blatantly false statement.

Further, the AJC article plainly states that DL will allow earning of miles, lounge access, etc., which is really the whole point of this thread.
