The Guaranteed Minimum Price is a commitment by Iberia.com to offer the best price available on flights originating in Spain.
If you buy your ticket on Iberia.com and that same day you find the same flight for the same dates at least 5 euros cheaper on another Spanish website, we'll refund the difference between the two fares.
You have to request the refund online by filling in the Claim Form on Iberia.com before midnight on the day of your purchase.
