CX from LHR - SYD Awesome!
Rich - I think the one flight number rule between AUS and EUR got changed sometime between December and June. At one point it was there while I was planning mine and then it changed. Good news.
Now if the rule about entering ANY continent more than once is OK (as long as it is a connection) is true, then I will be a happy camper. That would mean you can now go LHR - SEZ - LHR - JNB legally. Or if you were a CX fan, you could fly SYD - PER via HKG ( if you really, really liked CX). But I will believe it when I have my ticket in hand.
