I've just been looking at a few dummy bookings, please correct me if I'm wrong.
Ratio of Amex MR ascent to Emirates points is 4:3
Flying F long haul to Europe via Emirates is approx 400k emirates miles plus $1600 aud in taxes/surcharges
However book using Qff points, it's roughly the same 400k Qff points plus $1600 in taxes
That being said you need 533k amex Mr points to. Convert to Emirates miles
For the same flight
