SOFORT Banking is an online payment system certified by the German organisation TÜV Saarland. It is based on internet banking services that use PIN or TAN codes to access accounts, guaranteeing fast and secure online purchases.
All you need is a bank account at one of the supported (which means most banks in Spain). Payment is made in three easy steps and there's no need to register.

SOFORT Banking may only be used for transactions in EUR and there is no fee for deposits.
If you select “Bank transfer (Sofort)” as your payment method, you will automatically be redirected to the Sofort page. Once you have finished the payment procedure, you will automatically go back to the Iberia booking confirmation page.
