Prize
Five prizes consisting of 120,000 Avios (enough, for example, for two people to fly from Rome to Madrid, or from Miami to Madrid in blue class). They may be exchanged for other itineraries so long as they meet the requirements of Iberia Plus.
The total quantity of Avios will be credited to the Winner’s Iberia Plus account.
– In order to participate in the Contest, it is not necessary to be a member of Iberia Plus, but each winner must be or become a member of the program in order to receive the prize.
