elal and tlv are a different world, but in a normal airport, you would normally be given the next flights as you wanted on full fare, on which you could collect miles.
problem here is that AA cannot create space by QF.
Does AA know, that you know that flights have been cancelled?
In other words (please other guys with experience help me out here), it maybe pays to go like nothing happened to the airport, where they will tell you the flight is cancelled, and hop, they put you on the next flight, with some compensation voucher + full fare + miles.
again, I wants someone to confirm that this works, especially since we are dealing with LY, TLV and a AA booking, and LY can say that it is not their ticket...
Also moish, please confirm whether AA knows that you are aware of the problem, meaning: did they add notes to the booking about you being aware...?
