Ministry of Public Works and Transport Order 3837/2006 establishes discounts on national airfares for members of families with recognised residence in Spain who have a Large Family Card issued by their autonomous community.

The discount applies, upon request of the beneficiary, to tickets issued in Spain for scheduled flights on all domestic routes. It affects all fares where the value is shown on the ticket, except in the case of Business class fares when the discount is limited to the amount applicable to the Full Economy fare.

The large family account is added to the resident account if both apply. Large family discounts cannot be applied retroactively.

The discount also applies to ticket management fees with the same maximum limits that apply to the resident discount.
