We were scheduled to fly Iberia from Chicago to Madrid (and return) and I was a bit nervous about reviews about the onboard experience. Our experience could not have been further from some of these reviews. Flight attendants were outstanding, attentive, and, on all flights, at least one checked in near the end to ensure that the experience was outstanding. The airline offers some of the best rates from the U.S. to Europe, especially in Business class and I would not hesitate to fly them again. I had no experience with customer service.
