Yes, you can absolutely put your toiletries in your personal bag, such as a backpack, purse, or laptop bag, provided they comply with standard aviation security rules. As of 2026, many major international airports have upgraded to CT scanners, which allow for larger quantities of liquids (sometimes up to 2 liters), but the standard "3-1-1" rule still applies at most secondary airports. This means liquids, gels, and aerosols must be in containers of 100ml (3.4 oz) or less and fit into a single, quart-sized clear plastic bag. Keeping these in your personal bag is a smart move for easy access during the flight or if you need to freshen up during a layover. Just ensure the bag is leak-proof to protect your electronics, and be prepared to pull the liquid bag out if you are at an airport that has not yet transitioned to the newer "keep-it-in-the-bag" screening technology.
