If I remember it correctly, last summer we had *A Viking fare departure from N.Europe to U.S. (ORD,MSP, etc), it was approx £500-600, I bought 2 tkts back then, it was a flash sale, I don't see any surprisingly low about this current fare. Is it a good value? Yes! But I don't feel it's an ultra low priced fare as to the previous AZ error fare. If AZ really needs to cancel my tkts, I will not feel extremely disappointed. It is what it is, honour the tkt or not. Just do not set up your expectation too high, it's an Alitalia fare after all.
