Through December 31, 2018, you can book a one-way in Iberia economy to Madrid from either New York, Chicago, or Boston for 8,500 Iberia Avios + $75 to $85 out of pocket, or a roundtrip between those US cities and the land of jamón and tapas for 17,000 Avios + $185 to $200 out of pocket. That's 50% off the standard price.

If you don't like gazpacho, it's not likely we'd be friends.
