The most common weight limits are 15 lb (6.8 kg), 18 lb (8 kg), and 22 lb (10kg), but you should always check with your airline before flying. In this article, we'll outline the carry on weight limits by airline and then give some advice on packing lighter.

In 2026, the global standard for a hand carry bag typically ranges between 7 kg and 10 kg, though this is becoming more strictly enforced by airlines using automated gate scales. Most low-cost carriers, particularly in Asia and Europe, adhere to a strict 7 kg (15 lbs) limit for economy passengers. Full-service airlines like Delta, Lufthansa, or Air India often allow up to 8 kg or 10 kg. For 2026, many Indian domestic carriers have standardized the limit at 7 kg, including your laptop bag and personal items within that total. Business and First Class passengers usually enjoy a more generous allowance, often up to 12 kg or 14 kg. It is a grounded "reality check" to weigh your bag at home; with modern lightweight hardshell carry-ons often weighing 2.5 kg empty, you effectively only have about 4.5 kg of actual packing capacity before hitting the most common limit.
