The Iberia Airlines Checked Baggage Policy varies by ticket class and route. Typically, Economy Class includes one checked bag weighing up to 23kg, while Business Class passengers may bring more. Oversized or overweight bags incur additional charges, so it’s wise to weigh luggage in advance. Iberia also allows special items like strollers, wheelchairs, and sports equipment under specific conditions. Advance online payments for extra baggage can save money compared to airport fees. Travelers are advised to consult Iberia's website or app for accurate baggage allowances based on their specific booking. Knowing the policy avoids last-minute complications at check-in.
