They may share service with BA when AA reinstates the route. However, I'd be surprized if BA had much in the way of crew in TLV.
Also, BA is to 1W what SQ is to *A. They're in the alliance, but they often play by slightly different rules.
And as far as earning miles accross the atlantic, yeah, it kinda stinks I can't fly BY for credit. But at least when I fly ANY 1W carrier I get my 100% elite bonus miles. [ Hope you don't mine that I borrowed your stick for a minute... ]
