The benefits of MR First and Membership Rewards are virtually identical, the only difference being that you can’t use regular Membership Rewards points on Platinum Concierge bookings. Furthermore, since this chart was published, Amex has allowed MR Select points to be transferred to frequent flyer programs as well.nnAll three types of MR points are now virtually indistinguishable to the cardholder.nnHowever, there’s still a difference in the system: you can’t always link points accounts from cards of two different tiers.nnMR Select points are earned on the American Express Cobalt Card, the American Express Business Edge Card, and the American Express Green Card. The Business Platinum Card earns MR First points, and all other cards earn regular MR points.nnNote that American Express doesn’t differentiate between each Membership Rewards tier in its marketing materials, so you should make sure you’re fully aware of what type of points you’re earning on a card before signing up.
