보조배터리를 위탁 수하물(부치는 짐)에 넣어도 되나요?

안 됩니다. 리튬이온 보조배터리는 화재 위험 때문에 위탁 수하물에 넣을 수 없고 반드시 기내로 가지고 타야 합니다. 100Wh 이하는 자유롭게, 100~160Wh는 항공사 승인 후 2개까지 반입할 수 있으며 160Wh를 넘으면 아예 반입이 불가합니다. Wh는 mAh × 전압(V) ÷ 1000으로 계산하며, 3.7V 기준 20,000mAh는 74Wh입니다.

특가 운임에도 위탁 수하물이 포함되나요?

국제선 LCC 특가·라이트 운임은 기내 수하물만 허용되고 무료 위탁이 포함되지 않는 경우가 많습니다. 결제 단계에서 수하물 요금이 따로 붙기 때문에 검색 화면의 최저가와 실제 결제 금액이 달라집니다. 예약 화면에서 "위탁 수하물 포함" 여부를 반드시 확인하세요.

초과 수하물 요금은 공항에서 내면 얼마나 더 비싼가요?

온라인 사전구매 대비 공항 현장 결제가 최대 50% 이상 비싼 것이 일반적입니다. 국제선 근거리 LCC 기준 사전구매는 kg당 6,000~12,000원 수준이지만 현장은 kg당 12,000~20,000원까지 올라갑니다. 짐이 무거울 것 같으면 출발 전 온라인으로 추가 수하물을 미리 구매하는 편이 훨씬 저렴합니다.
