Chase Sapphire Reserve cardholders have been able to earn three Chase Ultimate Rewards points per $1 spent on purchases made through United MileagePlus X (MPX) with merchants that would normally earn 3x. Likewise Chase Ink Plus cardholders have been able to earn 5x on categories that would normally earn 5x (e.g office supply stores). This has been a popular option since MPX stopped earning 5x on the American Express Platinum card. Sadly Chase cards are no longer earning these 3x/5x. We will update the payments workshop to reflect this.
