On most major airlines, there is no specific weight limit for a personal item, provided it fits completely under the seat in front of you and you can carry it yourself. However, this is shifting in 2026; many international and budget carriers (like Air France, KLM, or IndiGo) now enforce a combined weight limit for your carry-on bag and personal item, typically totaling 15 lbs to 26 lbs (7 kg to 12 kg). U.S. carriers like Delta, United, and American rarely weigh personal items, but if your bag appears visibly heavy or overstuffed, a gate agent may require it to be weighed or checked. As a general rule for 2026, keep your personal item under 11 lbs (5 kg) to avoid issues on international flights where "weight-based" cabin policies are becoming the industry standard.
