Carry-on baggage typically includes one piece weighing up to 10kg (22lbs) and a personal item. However, it's essential to verify specific allowances for your itinerary, as they can differ based on factors such as destination and ticket type. Asiana Airlines also offers additional baggage options for purchase and has regulations regarding oversized or excess baggage.
