Brazil's Santander Unlimited and Bradesco Aeternum cards compared for 2026 travel rewards

Two premium credit cards targeting high‑income Brazilians are contrasted ahead of 2026. The Santander Unlimited Dupla Oferta combines Visa Infinite and Mastercard Black, carries a R$2,400 annual fee (with possible reductions) and earns up to 3 points per US dollar on both domestic and international purchases. The Bradesco Aeternum Visa Infinite costs R$2,112 per year, offers 4 points per dollar on domestic spend and 5 points per dollar abroad, and provides a single‑brand Visa Airport Companion lounge program.

Both cards grant unlimited access to airport lounges, travel insurance, concierge services and other premium perks. Santander channels points through its Santander Rewards platform, allowing transfers to Smiles, LATAM Pass and Azul Fidelidade, while Bradesco’s points accrue in the Esfera program with broad airline transfer options and no point expiration. The comparison highlights Bradesco’s slightly lower fee and higher point rates, versus Santander’s dual‑brand flexibility and potential fee waivers for clients with strong banking relationships.
