Taking a cue from Rudi, I think it would be useful to find out the different prices of oneWorld Explorer fares in various parts of the globe. Also, what variations in rules might exist, particularly in relation to ff miles/status accumulation.

To start off, in Singapore the prices published for F/C/Y in SGD:

3 Continents $7,907 $5,796 $3,488
4 Continents $9,489 $6,780 $3,850
5 Continents $10,913 $7,800 $4,428
6 Continents $12,550 $8,970 $5,537

Status/Mileage accumulation is complex based on ff program and class of booking. e.g. an AA ff will receive miles and status for all AA flights, but for other oneWorld partner flights it depends on the airline and class of service. First and Business will give miles and status on all, Economy will give miles and status on some BA, all QF, all CP and no CX flights.

If others out there can post the info on their ff program I will collate and post a consolidated picture.
