How can I redeem my Renfe allowance through the app?

You must register or log in if you are already a user. Then, go to "Products and Services" from the bottom menu of the App, and you will see the "Discounts" section. Click on "Do you have a Renfe ticket?" and you can redeem your bonus.

You can only redeem your Renfe Allowance if you have used VIA-T. To learn how to redeem your allowance, check the specific section in the FAQs here.
