I need to travel to Europe between either 29 June and 3rd July 2018. Ultimately I need to end up in Milan, but am happy to fly to anywhere in Europe. Obviously I'd like to secure business class flights using the "Saver" fare. There seem to be some available, but not too much. Having not much experience with KrisFlyer, is it likely that there will be any more available over time, or should I just snap up what's available now?
