Europe to Australia with a stopover and 2 layovers (less than 24 hours) in O-class (OZ and TG). I did my homework and checked award availability earlier via ANA tool, so we went flight by flight and booked segment by segment. No stopover/layover questions asked. USD266 in taxes (per person). Good job US Airways... I am impressed^

EDIT - I just realized the Res agent put us on a wrong LO feeder flight - we now have 27 hours in PAR and, therefore, 2 stopovers in the itinerary - NICE
