When it comes to packing for a flight, there are certain restrictions on liquids that you need to be aware of. The Transportation Security Administration (TSA) has a 3-1-1 rule for liquids, aerosols, gels, creams, and pastes that you can bring in your hand luggage. This means that each passenger is limited to one quart-sized bag of these items, with each item weighing no more than 100 milliliters (3.4 ounces).The most common items that must comply with the 3-1-1 rule include toothpaste, shampoo, conditioner, mouthwash, and lotion. Alcohol, perfume, and other tax-free liquids that you buy at the airport are allowed on the plane in hand luggage.
However, remember to leave the receipt inside the safety bag. If you have a connecting flight at another airport, you may have to put it in your checked baggage for the next leg of the trip. It's important to be aware of these restrictions when packing for a flight. Make sure that all of your liquids are in containers that hold up to 3.4 ounces and fit in a quart-sized bag. This will help ensure that your items are compliant with TSA regulations and make your journey through security as smooth as possible.
