Biggest Ever Purchase on a Credit/Charge Card?

I understand that it is $2.5m for a painting on an AMEX card.

Which brings me toa an interesting question, the above trasaction woulfd hav earnt the cardholder 2.5m Membership rewards points. Enough for 25 Upper Class Roundtrip Flights to anywhere in the US from London. Now these would have an approx value of $150,000 (25*6000). Now does this mean AMEX is at a loss because if they made they std 3% handling charge on the purchase, they would have got $75k from the merchant?

Or has my maths gone wrong somewhere in the process?

Thanks,
Richard
