Why We Like It

‍

This section breaks down the key reasons why we like the Iberia Visa Signature® Card.

‍

• You can earn 3 Avios per dollar on purchases with Iberia and its airline partners, plus 2 Avios per dollar on hotel stays booked directly.
• While the card has an annual fee, it charges no foreign transaction fees and provides a 10% discount on eligible Iberia flights.
• Spending $30,000 on purchases in a calendar year earns a $1,000 discount voucher, which more than covers the card's annual fee (publisher-formulated estimate).

‍

Pros

• Flexible rewards that can be transferred between several airline loyalty programs.
• Exclusive cardholder discounts on flights and a valuable annual companion voucher.

‍

Cons

‍

• Lacks common airline card benefits like priority boarding or a free checked bag.
• Redeeming rewards can be challenging due to a clunky website and restrictive booking requirements on partner airlines.
• The card's discount voucher is limited to bookings for two, offering little value for solo travelers.
