Air travel is full of rules and regulations, but many passengers aren't aware of the legal items they can actually take on board. While some airport restrictions seem obvious, others are less clear, leading to confusion over what is and isn't allowed. For example, many people assume that certain food items, liquids, or personal items are prohibited, when in fact they’re perfectly acceptable to bring on board. Knowing the ins and outs of what’s legally allowed can make air travel much easier, especially for those who love to keep snacks, entertainment, or personal care items handy during the flight.
Here are 11 surprising items that are completely legal to take from planes, things most passengers don’t realize they can pack. Whether it’s for comfort, convenience, or just curiosity, knowing these rules will help you enjoy your flight with fewer restrictions and less stress. Before your next trip, check out this list and see what you can legally bring!
Slippers
Slippers are commonly offered on long-haul international flights, especially in business or first class. These are provided for in-flight comfort, allowing passengers to remove their shoes and relax more easily, particularly during overnight journeys. Made of soft foam or thin fabric, they are lightweight and not intended for extended use. However, they are considered single-use and are not collected at the end of the flight. Some airlines may also give slippers to economy passengers on longer routes. Since they are not reused and are part of your comfort kit, you’re welcome to take them with you after landing.
Socks and Eye Masks
Eye masks and socks are frequently included in amenity kits, especially on overnight or long-haul flights. These items are designed to help passengers sleep more comfortably and stay warm during cooler cabin temperatures. Usually made from lightweight materials, they are intended for single use and are not collected at the end of the flight. Since they are considered personal comfort items, you’re encouraged to take them with you. While the socks may not be durable for long-term wear, they’re great for travel days, and eye masks can continue to be used on future flights or in hotels.
Lip Balm and Skincare Samples
Amenity kits on many international flights often include travel-sized skincare items like lip balm, facial mist, or hand lotion. These are designed to help with dry skin during long flights and are often provided by partner skincare brands. All of these items come in sealed, single-use packaging and are not intended to be returned. Since they’re personal hygiene products, you’re free to pack them away for later use. These small containers are TSA-friendly and useful long after your trip ends—perfect for your purse, travel kit, or hotel nightstand while on the road.
Water Bottles
Sealed water bottles provided during a flight are for your personal use and can be taken without concern. They’re commonly distributed on long-haul flights or during nighttime service to help passengers stay hydrated. Since they are not reused and come in sealed packaging, you are welcome to carry them off the plane. Bottled water is especially useful during layovers or in airports where access to free water is limited. When traveling internationally, be mindful of customs regulations—some countries restrict liquid imports, including airline-provided water bottles, so check the rules before arriving.
Toothbrush and Toothpaste
Long-haul and overnight flights often include a small dental kit with a toothbrush and a travel-sized toothpaste. These are always intended for single use, come sealed in plastic, and are provided for your convenience. Airlines do not reuse them, and there’s no expectation to leave them behind. Whether used mid-flight or packed for later, these kits are especially helpful on long journeys with layovers or when freshening up after landing. Since they’re lightweight and TSA-compliant, they make a handy addition to your toiletry bag for the rest of your trip.
Pillows (if disposable)
In economy class on some long flights, passengers may receive plastic-wrapped pillows made from synthetic fill. These are often intended for one-time use and can be taken off the plane. However, in premium cabins, pillows are generally higher quality and made for reuse, often with removable covers that are laundered between flights. If your pillow feels soft but basic and came in sealed packaging, it's probably disposable. Reusable pillows will typically feel sturdier and are not individually wrapped. When in doubt, check with the cabin crew before taking it off the aircraft.

Earplugs
Earplugs are included in many amenity kits and help reduce cabin noise, making them useful for sleeping during the flight. They come individually wrapped or in small cases, usually made from foam or soft silicone. These are always considered personal hygiene items and are not reused by the airline. Whether you use them during the flight or not, you’re encouraged to keep them for future use. Earplugs are great not only on airplanes but also in hotels, buses, or other noisy environments where you need quiet rest. They’re lightweight and easy to carry for ongoing travel.
Blankets (on some flights)
Blankets vary by airline and cabin class. In economy, you’ll often receive a lightweight fleece or polyester blanket sealed in plastic. These are generally for single-use and can be taken with you after the flight. However, in business or first class, blankets are typically heavier, higher quality, and reused—these should be left on board. If the blanket was shrink-wrapped when handed to you, it’s likely disposable. If it feels like a hotel-style blanket with a cloth cover, it's part of the airline’s inventory. Ask a crew member if you’re unsure whether it’s okay to take.
Magazines (if not labeled ‘For In-Flight Use Only’)
Many seatback pockets contain airline magazines featuring travel articles, entertainment guides, and airline services. If a magazine doesn’t have a “Do Not Remove” or “Property of Airline” label, it’s typically okay to take. These are usually replaced regularly and are not expected to be reused by other passengers. However, items like safety cards, menus, and aircraft-specific information should always stay onboard. If you're unsure whether a magazine is yours to keep, check the cover or ask a flight attendant. In general, unlabeled magazines are meant for short-term use and are safe to take.
Headphones (on certain airlines)
Many airlines hand out basic wired headphones—usually wrapped in plastic—for use with the in-flight entertainment system. These are typically inexpensive and designed for one-time use, especially in economy class. Since they aren’t reused for hygiene reasons, passengers are generally free to keep them. However, if you're in business or first class and receive high-quality, noise-canceling headphones, those are the airline's property and are typically collected before landing. If you're unsure, a good guideline is: disposable, plastic-wrapped earbuds can be taken, while sturdier, premium models should be returned to the flight crew.
Packaged Snacks
Sealed snacks like pretzels, crackers, cookies, or granola bars are often handed out during flights and are meant for individual consumption. These items are not recollected, and if unopened, you’re welcome to take them with you after the flight. They’re handy to keep on hand during layovers or in case of delays. However, fresh items—like fruit, bread rolls, or perishable sandwiches—should typically be left behind, unless the crew says otherwise. If traveling internationally, remember to check local customs rules before carrying any food into another country, as some items may be restricted on arrival.
