The ticket is the contract of transport between the airline and the passenger whose name is shown on the ticket. A ticket is valid for transport for one year:  from the date of issue, provided no flight coupon has been used; or  from the date of use of the first coupon, provided it was used in the same year the ticket was issued. If your request is related to a flight date change, itinerary change or change of the maximum stay in the destination, contact any Iberia office to check the conditions of the fare purchased. If your ticket was issued by a travel agency and you have not yet begun your trip, contact the agency.
