200,000 AMEX MR Points = 2 Concorde RT
This seems to work:
Until Sept. 30th AMEX is allowing conversion of 1,000 MR points to 500 Starwood points, this is 50% more than usual. With this in mind do as follows:
1. Convert 200,000 AMEX MR points to 100,000 Starwood points.
2. Convert 100,000 Starwood points into 250,000 Qantas points. Note: Starwood throws in 5,000 Starwood points for every 20,000 Starwood points you convert.
3. This should add up to 250,000 Qantas points which can be used to get 2 BA 1st class awards, also usable for Concorde RT JFK-LHR.
