Hold luggage, also known as "checked baggage," refers to the larger suitcases and items that are stored in the aircraft's cargo hold rather than the overhead bins. In 2026, most airlines have standardized the weight limit for hold luggage at 23 kg (50 lbs) for economy passengers, with a maximum "individual item" cap of 32 kg (70 lbs) for safety. Once you drop your bag at the counter or kiosk, it travels through a high-speed "Baggage Handling System" (BHS) where it is scanned for explosives and sorted by flight number. Unlike carry-on bags, hold luggage allows you to transport large liquids, sharp objects, and bulky items, but you are strictly prohibited from packing lithium batteries or power banks in the hold due to the risk of "thermal runaway" fires.
