Amex Membership Rewards vs Citi ThankYou Points
Partners and sweet spots
Amex reaches more than 20 partners, the widest network around. Citi has fewer but includes Turkish Miles and Smiles, one of the best programs for booking United and Star Alliance flights cheaply, plus Avianca and others. For specific sweet spots, Citi can outshine Amex.
Earning and cost
Citi pairs the no-fee Double Cash, an effective 2 percent that converts to transferable points with a Strata Premier, with the mid-fee Strata Premier hub, a low-cost path to transferable points. Amex leans on the Gold and Platinum, which earn more in categories but cost more in fees.
Which to choose
Pick Amex for breadth, premium perks, and category earning. Pick Citi for strong transfer value at low cost, especially the Double Cash plus Strata Premier stack. See the ecosystem ranking to compare.
