All Iberia staff with whom we interacted, including the flight crew, were helpful, kind, and professional. The plane looked practically new and was very clean. The seats were comfortable, and there was a lot of legroom in our emergency row seats. Our vegan dinner was quite good (rice with vegetables and grilled tofu, a fresh salad, and fresh fruit), but the breakfast snack seemed unappealing. Overall, this flight from Boston to Madrid was a great value.
