Iberia Plus Clásica cards never expire. For all other levels you can find the expiry date on the digital card that you can find by logging in to Iberia Plus > My Iberia Plus > Iberia Plus Card.
When you card expires, you can download your digital card again with the new expiry date and remove the expired card.

As part of our goal to become climate neutral, all our cards are digital. It helps us to avoid using plastic and you receive it immediately on your mobile device.
