This time we have a sale with Iberia and LATAM from Rio de Janeiro, Brazil to Madrid. The interesting item is that they are flights operated by Iberia but sold by LATAM. This might complicate mileage earnings.
Here you can find a trip report on Iberia in Business Class from New York JFK to Madrid (MAD) and reviews of the Schengen lounge and Non-Schengen lounges at Madrid-Barajas.
