There's a thread about Swiss, on the AA forum, that raves about F & J on the A340 from LAX-ZRH (5x/week, not daily). IIRC, it also says that Swiss uses the A340 for ZRH-TLV, and sells the J cabin as Y. I think both flights are AA coded, so that probably maxes your mileage.

That said, I've looked at this a bunch of times, and there are no really good connections that earn you status miles.
