What documents do I need to present to prove that I am a Large Family?

Before boarding, you must show the original or a certified copy of the large family certificate issued by your Autonomous Community.

The discount depends on the type of large family:

• General Large Family (Type I): 5% off the fare.
• Special Large Family (Type II): 10% off the fare.

If you cannot prove that you are a large family, you will not be able to use your ticket and will have to purchase another one at the fare available at that time.

The regulations governing discounts for large families on flights are Order FOM/3837/2006 and Royal Decree 1621/2005, with their amendments. You can consult them here.
