In 2026, checked bags are typically charged based on a per-bag fee rather than a "per-pound" rate, but they are subject to strict weight ceilings. For most domestic and international Economy flights, the standard weight limit is 50 pounds (23 kg) per bag. If your bag exceeds this limit, you will be hit with an "Overweight Baggage" fee, which can range from $100 to $200 per bag. Some airlines, particularly in Europe and Asia, do offer "Weight Concept" fares where you are given a total weight allowance (e.g., 30 kg) that can be spread across multiple pieces. In 2026, many Indian domestic carriers charge ₹500 + GST per extra kg if you exceed your pre-booked allowance. For Premium Economy, Business, or First Class, the limit is often raised to 70 pounds (32 kg) per bag. It is almost always cheaper to pre-book extra weight or an additional bag online rather than paying the inflated "at-the-counter" rates. Additionally, bags that are both overweight and oversized (exceeding 62 linear inches) will incur double penalties, making it more economical to split your belongings into two smaller, lighter suitcases.
