I reckon I can top these fares

Just returned from NZ

Melbourne to Auckland roudn trip with United A$99 (US$62) [Thats Return!] Total 3288 miles

plus

Got 5000 bonus miles for joining Mileage Plus
and
3288 miles for the trip

Also I saw recently a Melbourne to Singapore special 2 for 1 offer flying Emirates. @ return economy tickets for $777 total which is about US$225 return for each passenger.

No FF program with Emirates though...
