In 2026, if your carry-on exceeds the airline's weight limit (typically 7kg to 10kg for international or budget carriers), the airline will most likely force you to gate-check the bag. Because overhead bins have weight capacities for safety, a "heavy" bag is viewed as a liability. If you are forced to check the bag at the gate, be prepared for a "Gate Handling Fee" which in 2026 can range from $50 to $100, often significantly more than if you had checked it at the main counter. A "pro-tip" to avoid this is the "Heavy Coat" trick: wear your heaviest items or stuff your pockets with dense electronics (like power banks or cameras) during the weigh-in, as airlines rarely weigh the passenger. Alternatively, use a "personal item" backpack for your heaviest items, as these are weighed less frequently than roller bags. Most importantly, if you are forced to check it, immediately remove your lithium batteries, power banks, and medications, as these are strictly prohibited in the cargo hold for fire safety reasons.
