In 2026, checked luggage weight limits vary by airline and cabin class, but the "standard" limit for Economy Class is 23 kg (50 lbs) per bag. If you are flying in Business or First Class, many airlines increase this allowance to 32 kg (70 lbs) per piece. It is important to note that for safety reasons related to baggage handlers, almost no airline will accept a single bag weighing more than 32 kg, even if you are willing to pay an overweight fee; such heavy items must often be shipped as cargo. Budget carriers (like Ryanair or Spirit) frequently offer tiered options where you can pay for specific weights, such as 15 kg or 20 kg. Exceeding your pre-booked or allowed weight can result in steep fees, often ranging from $15 to $100 depending on the airline and the distance of the flight.
