The Amex Trifecta, Explained

By Bryce Casson, Founder · Cardocrat · Updated August 2026
The short answer: The Amex trifecta pairs the Gold (4x dining and groceries), the Platinum (5x flights plus premium perks), and a business card like the Blue Business Plus (2x on everything) so all your spending earns Membership Rewards, which transfer to airline partners for premium-cabin value.

The cards and what each does

The trio: the Amex Gold for 4x at restaurants and U.S. supermarkets, the Amex Platinum for 5x on flights plus lounges and credits, and the Blue Business Plus for 2x on everything else (a flat-rate catch-all with no annual fee). Together they cover dining, groceries, travel, and general spend, all earning Membership Rewards.

Why it works

Each card earns the same Membership Rewards, which pool and transfer to a deep list of airline partners for premium-cabin awards worth several cents per point. The Gold and Platinum carry fees, but the Gold dining and grocery credits and the Platinum travel and lifestyle credits offset much of the cost if you use them.

Mind the Amex rules

Apply bottom-up to respect the Amex family rule (holding the Platinum can block the Gold welcome bonus) and the once-per-lifetime rule. The Blue Business Plus is easy to add and caps 2x at a generous annual limit. Model the combo in the wallet builder. See all card combinations.

The Amex Gold (4x dining and groceries), the Platinum (5x flights plus premium perks), and a business card like the Blue Business Plus (2x everything). All earn transferable Membership Rewards.
In what order should I get the Amex trifecta cards?
Bottom-up: get the Gold (and any lower MR cards) before the Platinum, because the Amex family rule means holding a more premium card can block the welcome bonus on a lower one.
