In 2026, the standard weight limit for checked baggage on most international "full-service" airlines (like Air India, United, or KLM) is 23 kg (50 lbs) per bag for Economy class. This is part of a global industry standard designed to protect the health and safety of baggage handlers. If you are flying Business or First Class, this limit is often increased to 32 kg (70 lbs) per bag. However, "Low-Cost Carriers" (LCCs) like IndiGo, Ryanair, or Spirit often have much stricter or tiered limits; for example, a standard domestic "Saver" fare in India might only include 15 kg, with any additional weight requiring a pre-paid fee. Some airlines also implement a "piece concept" versus a "weight concept"; on the piece concept (common for flights to the USA), you might be allowed two bags of 23 kg each, whereas the weight concept (common in Asia and Europe) gives you a total weight allowance (e.g., 30 kg) that can be spread across multiple bags. Always check your specific e-ticket, as exceeding the limit by even 1 kg in 2026 can result in heavy "excess baggage" fees, often starting at $15–$25 per extra kilogram.
