The term "1PC" (One Piece) on your airline ticket indicates that your fare includes the right to check one bag in the aircraft's cargo hold at no additional cost. For standard economy class in 2026, this "piece" is generally restricted to a maximum weight of 50 lbs (23 kg) and a total size of 62 linear inches (length + width + height), including wheels and handles. For business or first-class passengers, the weight limit per piece often increases to 70 lbs (32 kg). If your bag exceeds these limits, you may face "oversized" or "overweight" baggage fees even if you only have one item. It is important to note that a single piece cannot be made up of two smaller bags taped or strapped together; it must be a single, distinct unit. Many "Basic Economy" fares in 2026 do not include 1PC, requiring you to pay a fee if you need to check any luggage, so always verify your specific fare rules before arriving at the airport.
