The weight limits for checked baggage generally range from 20 to 30 kilograms per piece. Passengers should verify their specific baggage allowance based on their ticket type and route when booking their flights. Exceeding the weight limit or the allowed number of pieces may result in additional fees. It's important for passengers to ensure that their checked luggage complies with size restrictions to avoid any issues during check-in and boarding. For accurate information, passengers should consult Batik Air's official website or contact customer service.
