Iberia is offering 10%-20% off select award flights when you book by todya, September 23, 2026, for travel through March 18, 2027. The sale excludes holiday travel from December 18 through January 12. You can find 20% off economy awards from Boston, New York, and Washington; 15% off economy from cities including Chicago, Miami, Los Angeles, Orlando, San Juan, and Toronto; and 10% off select business-class awards from Boston, New York, Chicago, Orlando, San Juan, and Toronto. The most interesting opportunity is stacking the sale with the current 30% Amex Membership Rewards transfer bonus to Avios. For example, an off-peak Boston-to-Madrid business-class award that normally costs 40,500 Avios drops to 36,450 Avios with the sale, requiring only about 28,039 Amex points with the transfer bonus. Economy awards from the East Coast can also drop below 10,000 Amex points one way after stacking both promotions. The catch is that the award sale ends today, so this is one to act on quickly if you find availability that works.
