Asiana baggage allowance varies based on the travel class and route. For international flights in Economy Class, passengers typically have a checked baggage allowance ranging from 20 to 30 kilograms, while in Premium Classes, the allowance is often more generous. Cabin baggage dimensions are generally restricted to 115cm (length + width + height), and the number of items allowed may differ by class. Excess baggage may be subject to additional fees. It’s crucial for passengers to check the specific details of Asiana Airlines’ baggage allowance on their official website or contact the airline directly, as policies can be subject to change and may vary based on the specific route or ticket type.
