Amex companion voucher - world record attempt
I'm setting up to earn and spend an amex companion voucher in the least possible time.
Earning year starts in about 11 days. I'm going to try and earn the voucher in one single transaction and then spend it as soon as possible.
Anyone done this before and know the shortest time achievable ? I reckon to be able to do it in about 25 hours but it might be a bit longer because it's on the weekend.
