Airport security is an important aspect of air travel, and understanding what is allowed through security checkpoints can help ease travel experiences. The Transportation Security Administration (TSA) in the United States provides guidelines on permitted and prohibited items in carry-on and checked baggage, including liquids, electronics, sporting equipment, and medical devices. Similar guidelines exist worldwide, such as restrictions on carrying liquids in Europe. It is essential to properly pack allowed items to facilitate the screening process. Even generally permitted items may be subject to additional screening or prohibited if they trigger alarms, appear tampered with, or pose security concerns. Ultimately, the decision rests with TSA officers, who may request to power up electronic devices. Passengers can also refer to the TSA's `What Can I Bring?` page and seek assistance from the AskTSA team for specific item inquiries.

What You'll Learn

Electronics
When going through airport security, you will be required to remove all electronic devices larger than a mobile phone from your carry-on bag and place them in a bin for X-ray screening. This includes items such as laptops, tablets, e-readers, and handheld game consoles. These measures have been implemented by the Transportation Security Administration (TSA) to enhance security and obtain clearer X-ray images.
It is important to note that electronic cigarettes and devices containing lithium-ion batteries are not allowed in checked bags. These items must be placed in carry-on luggage, and you are not permitted to use them onboard the flight. Additionally, batteries should be removed from devices in checked bags and placed in carry-on luggage, following the airline's lithium battery acceptance policy.
If you are enrolled in TSA PreCheck, you may be exempt from removing your electronics from your carry-on bag during the screening process. TSA PreCheck is available at 200 airports nationwide and allows low-risk travelers to expedite their security screening. However, it is important to note that not all individuals with TSA PreCheck are guaranteed expedited screening, as the TSA uses unpredictable security measures.
To ensure a smooth process when traveling with electronics, it is recommended to familiarize yourself with the specific guidelines provided by the TSA and your chosen airline. These guidelines are subject to change, so staying informed about the latest updates is essential. Additionally, if you are traveling internationally, remember to review the regulations of your destination country regarding electronic devices and batteries.

Liquids
In general, you are allowed to bring a quart-sized (1-litre) bag of liquids in your carry-on luggage. This includes aerosols, gels, creams and pastes. Each container must be 3.4 ounces (100ml) or less and all containers must fit inside the same clear, resealable plastic bag. Any containers over 100ml can be placed in your hold luggage, as long as they are not prohibited items. This includes beverages, which must be discarded before passing through security.
There are some exemptions to the liquid restrictions. Medication is a common example of an item that can be taken through security in quantities above 100ml. It is recommended that medication is clearly labelled and you may be asked to open the container for a vapour analysis. Baby food, milk, liquid formula, water and juice are also allowed in quantities above 100ml if you are travelling with a baby or toddler.
Liquid souvenirs can also be taken through security if they are sealed in a security tamper-evident bag (STEB).

Food
When it comes to food, the TSA allows most items through its security checkpoints. However, there are some important exceptions and rules to be aware of. The key consideration is whether the food is a liquid or has a high liquid concentration.
The 3-1-1 rule applies to liquids, creams, and spreadable items with a soft consistency, such as peanut butter, hummus, olive oil, salsa, jams, and yogurt. These foods are permitted in checked luggage in any quantity. However, to bring them in carry-on luggage, they must be in containers of 3.4 ounces (100ml) or less, and they must fit into a single quart-sized bag.
It is important to note that while most foods are allowed, certain items may be subject to additional screening or may not be allowed if they trigger an alarm during screening, appear tampered with, or pose security concerns. Additionally, while there is no limit on the amount of breast milk, baby formula, and baby/toddler food you can bring, they must be in containers of 3.4 ounces (100ml) or less. Alcoholic beverages over 140 proof (70% alcohol by volume) are prohibited in both checked and carry-on luggage, but smaller bottles of lower-proof alcohol are generally permitted.
If you are unsure about a specific food item, you can consult the TSA's "What Can I Bring?" tool or contact their AskTSA team, which is available 365 days a year.

Clothing
When going through airport security, it's important to wear clothing that will allow you to get through security checks quickly and efficiently. Here are some tips to keep in mind when choosing your travel outfit:
Shoes
Most airport securities require you to remove your shoes temporarily, so it's best to wear slip-on shoes that are easy to take on and off. Simple loafers, ballerinas, espadrilles, or slip-on sneakers are good options. Avoid shoes with excessive ties, laces, and closures, such as boots or high-top sneakers, as they can slow down the security line. Additionally, shoes with metal details, such as studs or buckles, can set off the metal detector, requiring additional screening.
Outerwear
You will typically need to remove coats and jackets, including bulky outerwear like hoodies, parkas, and vests, before passing through the metal detector or body scanner. Bulky or oversized clothing may require extra screening, as they can be used to hide prohibited items. If you're wearing a sweatshirt, consider adding a shirt underneath in case you're asked to remove your outer layer.
Pants
Avoid pants with excessive pockets, zippers, or metal details, such as cargo or army pants, as they can set off the metal detector. Opt for sweat or track pants instead, which have fewer pockets and details. Belts are not permitted through airport security due to their metal clasps, so choose a belt-free outfit or be prepared to remove your belt before passing through the metal detector.
Accessories
Metal jewelry and piercings can set off the metal detector, leading to additional screening. If you're wearing metal piercings that cannot be removed, you may request a private screening. Large earrings, necklaces, bracelets, and rings made of metal should be removed before passing through security. Opt for accessories made of plastic or non-metal materials if possible.
In general, it's best to wear clothing that is comfortable yet relatively close-fitting. Avoid baggy or loose clothing, such as low-hanging pants, flowy skirts, or loose dresses, as they may require additional screening.

Sporting equipment
When packing sporting equipment in your luggage, it's important to plan ahead and pack properly to facilitate the screening process and ease your travel experience at the airport. Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm, appears tampered with, or poses security concerns. The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
For those interested in camping and fishing, it is recommended to call your airline in advance to double-check if your gear is allowed on the plane. Basic items such as trekking and hiking poles or insect repellent (3.4 oz or less) are permitted in your checked bag. Camping items such as fuel, burning paste, and gel fire starters are illegal to bring on the plane. Fishing rods and tackle are allowed on the plane but should be securely packed in your checked luggage.
If you're a diver, it is recommended to bring both a carry-on bag and a checked bag. Expensive equipment such as dive computers and regulators should be packed in your carry-on bag, while items such as your dive jacket, wetsuit, fins, and mask should be packed in your checked bag.
Golfing equipment, including golf clubs, balls, tees, and shoes, can be checked in as part of your checked baggage allowance. If you're travelling with a golf umbrella, it will need to be checked in separately and will count as an additional item.
For those interested in racquet sports, a sports racquet can be carried in your hand baggage if it is in a slim protective case and stowed in the overhead lockers. The case should contain a maximum of two racquets and no additional items such as balls or clothing. If you have three or more racquets, they must be checked into the hold as part of your checked baggage allowance.
Larger sporting equipment such as surfboards, kayaks, and canoes need to be booked in as cargo.
