SENSATIONAL BA/oneworld business fares: Stockholm to Buenos Aires from £1,382 return

Some truly SENSATIONAL oneworld business class fares to Buenos Aires, Argentina have popped up...

I have been able to find Stockholm (ARN) to Buenos Aires (EZE) from £1,382 return (Momondo.co.uk):

The outbound is with BA from Stockholm via London to Buenos Aires. On the return, you'll fly LATAM to Rio de Janeiro, then continue to Stockholm via London on BA:

The extra LATAM segment on the return doesn't bother us as we'll be rewarded with an additional 40 tier points if credited to the BA Executive Club. This routing will thus earn a total of 440 tier points (outbound: 40 + 160; inbound: 40 + 160 + 40).

If you don't care about status, consider crediting these flights to Alaska. You'll earn a whopping 250% of the miles flown.
