Thanks for the confirmation!
I understand that the First class trip would be getting the best possible value from that discount for that trip, but we don't have the 240,000 points now, and if we wait until we get them we might miss out on availability. We may also want to take a trip to SFO or LAX in the meantime, so lay-flat business will have to do. ;-)
On a similar subject, are the Amex 2-4-1 vouchers useable for *A RTW packages?
The MasterCard discount applies for award travel on SAS. No code-shares, has to be SAS themselves. Only for points bookings, not regular tickets (so not for points+money).
And you're correct, a business award to Auckland will be 180,000 points with an Amex 2-4-1 voucher in business, or 240,000 in first. Which would be the best possible way to use the 2-4-1, and the best possible discount for that trip, both at once
(and the MasterCard discount wouldn't be usable here, since SAS don't fly to Auckland themselves)
