The Transportation Security Administration (TSA) provides an extensive list of items that travellers can and cannot bring in their carry-on and checked baggage. The list includes common items such as liquids, electronics, sporting equipment, and medical devices. Some items prohibited by the TSA include flammable substances, bear spray, firearms, ammunition, and hazardous materials. It's important to note that the list of prohibited items may vary by country and is subject to change over time. Travellers can consult the TSA website or other official sources for the most up-to-date information on what is and isn't allowed through airport security. Additionally, programs like TSA PreCheck allow travellers to expedite the security process by bypassing certain steps, such as removing shoes, laptops, and belts.

What You'll Learn

Electronics
When it comes to electronics, there are some considerations to keep in mind when passing through airport security. Firstly, it is recommended to have these items readily accessible, as they will need to undergo separate screening. This includes devices such as laptops, tablets, e-readers, and handheld game consoles. Some airports may require you to remove these larger electronic devices from your carry-on bag and place them in a bin for X-ray screening.
It is important to note that the screening process may vary depending on the airport and country. For instance, in the United States, the Transportation Security Administration (TSA) may implement enhanced security measures at certain airports, resulting in a more extensive screening process for personal electronic devices. Additionally, some airports in the US have upgraded to 3D X-ray machines, which may not require the removal of electronics from your bag. However, it is always a good idea to be prepared and have your electronics easily accessible.
Another factor to consider is the size of your electronic devices. As a general rule, items larger than a standard smartphone or camera may need to be removed from your bag. This includes devices such as tablets, laptops, and DVD players. Smaller electronics, such as smartphones, cameras, Nintendo DS, and handheld gaming consoles, may sometimes be allowed to stay in your bag, but it is often easier to remove them beforehand to avoid any delays.
Additionally, it is important to properly insure your electronic devices, especially the more expensive ones like laptops and tablets. Consider adding a gadget insurance add-on to your travel insurance to cover these items in case of confiscation or damage. Check with your chosen airport to understand their procedures for confiscated devices, as some may offer the option to have the item sent to your address.

Clothing
When going through airport security, it is best to wear simple, uncomplicated clothing. While there are no specific restrictions on clothing, wearing certain items may slow you down or cause additional screening.
Firstly, it is important to note that you will be required to remove outerwear such as coats, jackets, and hoodies. This includes light jackets and blazers. So, it is advisable to carry these items rather than wear them. Additionally, you will be asked to remove belts, as their metal clasps can set off the metal detector. Even non-metal belts may need to be removed.
Secondly, avoid wearing complex or heavy shoes. Most airports require you to remove your shoes for screening, so opt for slip-on shoes that are easy to take off and put back on. Safety boots with steel toe caps, for example, are not recommended.
Thirdly, loose or baggy clothing may require additional screening or a pat-down inspection. This includes items such as low-hanging pants, flowy skirts, oversized sweaters, sweatshirts, and loose dresses. If your clothing is too loose, security agents may suspect you of concealing prohibited items. Similarly, clothing with metal fasteners or buttons may require additional screening, as they can set off the metal detector.
Lastly, avoid wearing metal jewelry, piercings, or hair accessories as these can also trigger the metal detector. If you are wearing a hoodie or sweater, it is advisable to wear a t-shirt or another garment underneath in case you are asked to remove the top layer. Offensive or threatening messages on clothing may also draw unwanted attention from security agents and could get you pulled aside for additional screening.

Food
It is recommended to place food items in a separate, easily accessible section of your bag. TSA agents may ask you to remove them during screening, especially if they are wrapped in foil or contain metal, as this may trigger the metal detector and require additional inspection. Clear containers can make the inspection process easier. If you have special dietary needs, you can bring your own food, but it must go through the X-ray machine for screening.
It is important to note that even if a food item is generally permitted, it may be subject to additional screening or confiscation if it triggers an alarm, appears tampered with, or poses security concerns. Planning ahead and organizing your bag accordingly can help speed up your experience at airport security.

Marijuana
While TSA security officers do not search specifically for marijuana or other illegal drugs, if any illegal substances are discovered during security screening, they are required by law to notify local law enforcement. The final decision on whether an item is allowed through the checkpoint rests with the TSA officer.
It is important to note that federal law classifies marijuana with over 0.3% THC as a Schedule I drug under the federal Controlled Substances Act of 1970. TSA explains that marijuana and certain cannabis-infused products, including some Cannabidiol (CBD) oil, remain illegal under federal law. However, you are allowed to bring cannabis products containing no more than 0.3% THC on a dry weight basis or those approved by the FDA in your carry-on or checked luggage.
Some airports, like Chicago's O'Hare, offer cannabis amnesty boxes where travelers can dispose of their weed before going through TSA. Ultimately, TSA's primary focus is on terrorism and security threats to aircraft and passengers, and there are limited resources available to check for personal possession of drugs. However, travelers should be cautious as marijuana possession can still lead to criminal charges, and the decision to allow it through security checkpoints rests with law enforcement.

Jewellery
When travelling with jewellery, it is recommended to keep valuable items with you at all times and not in checked baggage. You can ask the TSA officer to screen you and your valuables in private. It is important to be aware of the rules specific to your airport, as they may vary.
Generally, you can wear most types of jewellery, including pieces made from precious metals like gold and silver. Costume jewellery is also typically permitted, but be cautious with oversized or intricate designs, as they may set off metal detectors. When it comes to earrings, necklaces, and bracelets, you shouldn't face any issues, but keep in mind that simpler styles are less likely to raise eyebrows. Small, non-metallic jewellery can pass through security without any issues.
Larger pieces of jewellery, like chunky necklaces, might raise alarms during the screening. If you can, keep your jewellery minimal or opt for lighter pieces to streamline your passage through security. When you approach the metal detector, be prepared to remove any significant items if requested. Metal detectors sometimes pick up heavy rhinestones or metal buttons on jeans, so they will definitely notice a piece of jewellery in your pockets. It is recommended to put jewellery in your carry-on luggage and not in your pocket.
If you are wearing a pendant, you should consider swinging it around so it's on your back instead of your chest. It's easier and quicker to pat down the back than the chest/breast of a passenger. If you prefer not to be touched, then remove your jewellery prior to the body scanner and place it inside your bag.
