American Express has long offered generous referral bonuses and those bonuses have only gotten more interesting ever since Amex started allow you to refer from your card to many other cards (in some cases being able to refer someone to almost any Amex card and receive the bonus specific to the card you refer from – see this post for more details).
However, Milenomics reported how it has gotten significantly better this month with the ability for some cardmembers to also earn 3 extra points per dollar on all spend for three months after a successful referral by 10/28/20 (we posted about this deal here). This stacks on top of the usual referral bonus and it makes for a great deal. This means that most Membership Rewards cards earn a base of 4x Membership Rewards points per dollar spent for three months after you refer someone — and when you add 3 more points on top of a bonus category, it only gets better. Milenomics has a good deal of early info in terms of how quickly bonus points post as well as some smart strategy in terms of which card(s) it might make sense to use to generate a referral for this promo. See their post for full details.
Interestingly, this extra-three-point bonus isn’t limited to Membership Rewards-earning cards: you can also get three extra miles or hotel points per dollar spend on co-branded cards. That could make for a great deal for those spending toward Delta elite status or toward a free night certificate on a Hilton Surpass card. In fact, given that Hilton free weekend night certificates earned by the end of this year are good for any night of the week and valid for two years, it makes sense for anyone with a Surpass to be looking at completing that $15K spend. Earning an extra 3 points per dollar spent while doing it might make sense. Three extra Hilton points per dollar is clearly worth less than three extra Membership Rewards points overall, but considering the value of the free night certificate, that might be a strategy to pursue.
