For those committing to carry-on bags, personal care items often present the biggest packing challenge. While hotels typically provide basic toiletries, travelers often prefer their own specific products. The Transportation Security Administration (TSA) mandates a clear set of guidelines for liquids, aerosols, gels, creams, and pastes: containers must not exceed 3.4 ounces (100 milliliters) and must fit comfortably into a single quart-sized, clear, resealable bag. Each passenger is permitted one such bag. It's crucial to note that this restriction applies to container size, not merely the amount of liquid inside; a partially filled larger bottle is not allowed.
When it comes to hair cleansing products, traditional liquid shampoos must adhere to the aforementioned 3-1-1 rule. Alternative options like solid shampoo bars offer a convenient way to bypass liquid restrictions, with many beauty retailers offering a variety of choices. Refillable travel-sized bottles, such as those from brands like Cadence, provide a leak-proof solution for decanting your preferred liquid hair products. Given the variability in hotel offerings, it's also advisable to pack your own hair conditioner, following the same liquid guidelines. Dry shampoo, if in liquid or aerosol form, also falls under the 3-1-1 rule and must be capped securely if an aerosol to prevent accidental discharge.
The permissibility of makeup depends on its form. Solid makeup items are generally exempt from liquid restrictions, offering greater packing flexibility. However, liquid cosmetics such as foundations, mascaras, eyeliners, and nail polishes are subject to the 3-1-1 rule and must be contained within the quart-sized bag. Similarly, liquid body wash adheres to these limitations; a solid bar of soap presents an easier, unrestricted alternative. Liquid makeup removers also fall under the liquid rule, making travel-sized options or makeup wipes a practical choice. For deodorants, stick varieties are universally permitted without size constraints, whereas gel, spray, or lotion deodorants must conform to the 3-1-1 guideline.
Sunscreen, a vital travel companion, also falls under the 3-1-1 liquid rule. For extended trips or frequent application, consider purchasing larger quantities upon arrival at your destination. Travelers with contact lenses can carry them without issue, but contact lens solution must abide by the 3-1-1 rule, and it is recommended to buy sealed travel-sized bottles for sterility. Alcoholic beverages in carry-on bags are restricted to 3.4-ounce sealed containers and cannot be consumed during the flight. Stronger alcoholic beverages (over 70% alcohol by volume) are prohibited entirely from carry-on luggage. Duty-free alcohol purchased at airports is permitted if it remains in its sealed, transparent bag.
Beyond liquids, travelers frequently inquire about small personal grooming tools. Nail clippers are generally allowed in carry-on baggage. The rules for razors are more nuanced: disposable and cartridge razors are typically permitted, but straight-edge razors and safety razors with removable blades are often prohibited in carry-ons due to security concerns. It is always advisable to consult official security guidelines, such as those provided by the TSA, for the most current and specific information regarding these items before your departure.
