Recall that American Express OPEN offers various cards for small businesses such as the American Express Business Platinum card and the American Express Business Gold Rewards card. Built-in to these business cards is an OPEN Savings benefit. This benefit provides either a 5% discount or 2 additional Membership Rewards points for each eligible dollar spent at OPEN Savings travel partners.
One OPEN Savings partner, Hyatt Hotels & Resorts, will no longer be part of the OPEN Savings program beginning January 1, 2016. I personally have never taken advantage of this benefit with Amex/Hyatt anyway, but still think it is a negative with respect to the Amex business cards. 🙁
