Darren - thanks for the information.
What do the new rules say about transiting through the same city more than twice? In other words, can you do LHR-HKG-SYD-HKG-NRT-HKG-SFO-LHR, and therefore flying three times to/via HKG.
I remember someone posting here that you could only fly in/out any city twice in one OWE itinerary.
