Airport security is an essential but often confusing and stressful part of air travel. The Transportation Security Administration (TSA) in the US is responsible for ensuring the safety of the traveling public and preventing dangerous items from being carried onto planes. The list of prohibited items is extensive, and it is important for travelers to be aware of the restrictions to ensure a smooth journey through security. While some items are completely prohibited, others may be allowed if they meet certain conditions or are packed in a specific way. Understanding the rules and planning ahead can make the security process quicker and easier for travelers.

What You'll Learn
Liquids, gels and creams over 3.4 oz
Liquids, gels, and creams are subject to the TSA's 3-1-1 rule. This means that each container must hold no more than 3.4 ounces of liquid, gels, or creams, and all containers must fit into a quart-size bag. Each passenger is allowed one such bag. If you have liquids, gels, or creams in containers larger than 3.4 ounces, you will need to pack them in your checked baggage.
There are some exceptions to this rule. Duty-free liquids in secure, tamper-evident bags are allowed in carry-on luggage if they were purchased within 48 hours of boarding and do not show signs of tampering. Medications in liquid, gel, or aerosol form are also exempt from the 3.4-ounce limit, but they must be in a "reasonable quantity" for your trip. Frozen liquid items are also allowed through security as long as they are frozen solid.
It is important to note that 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 during screening, appears to have been tampered with, or poses security concerns. The final decision rests with the TSA officer at the checkpoint.

Sharp objects, e.g. knives, razors, scissors
To ensure a safe and seamless journey through airport security, it is important to understand the restrictions on sharp objects. Here is some detailed information about carrying sharp objects like knives, razors, and scissors onboard an aircraft:
Firstly, it is essential to know that sharp objects are generally prohibited in carry-on luggage. This includes a wide array of items, such as box cutters, ice axes, picks, knives (including pocket knives), meat cleavers, razor-type blades, and scissors that exceed four inches. These items must be packed in checked baggage instead. It is worth noting that plastic or round-bladed butter knives and small scissors (under four inches) are typically allowed in carry-on bags.
Additionally, any sharp objects packed in checked baggage must comply with specific guidelines. For example, knives and scissors must be sheathed or securely wrapped to prevent injury to baggage handlers and security personnel. It is also advisable to declare these items to the security officers during the screening process.
Furthermore, certain sharp medical devices may be allowed onboard aircraft but are subject to additional screening. These include items like syringes, pre-filled injection devices, and infusion pumps. However, it is crucial to declare these items before passing through security and to carry supporting documentation if possible.
Ultimately, the decision on whether an item can pass through airport security rests with the TSA officer. Even if an item is generally permitted, it may be prohibited if it triggers an alarm, appears tampered with, or raises security concerns. Therefore, it is always best to check with the TSA or local security authorities before packing sharp objects in either carry-on or checked baggage.
By following these guidelines and staying informed about airport security restrictions, passengers can ensure a smoother travel experience and avoid any issues related to sharp objects in their luggage.

Most tools
The Transportation Security Administration (TSA) outlines regulations for carrying household and tool items in both carry-on and checked baggage. TSA's screening procedures are designed to prevent prohibited items and security threats from entering the airport's sterile area. The TSA website provides a comprehensive list of items that travellers can and cannot bring, including guidelines on common items like liquids, electronics, sporting equipment, and medical devices.
When it comes to tools, the TSA generally allows small tools under 7 inches (17.78 cm) in carry-on baggage. This means that most standard-sized tools like screwdrivers, wrenches, hammers, and small utility knives would be permitted in your carry-on bag. However, it's important to note that any tools with blades or sharp edges may be subject to additional restrictions.
Tools with longer blades or those that could be considered potential weapons, such as knives, swords, or box cutters, are typically prohibited in carry-on baggage and must be packed in your checked luggage instead. Additionally, any tools that are powered by flammable gas or liquids, such as torches or soldering irons, are also prohibited in both carry-on and checked baggage.
It's always a good idea to check the TSA website or reach out to their AskTSA team for specific information about the tools you plan to bring. The final decision rests with the TSA officer at the checkpoint, and they may subject your tools to additional screening or prohibit them if they pose security concerns.

Vaping devices in checked luggage
Vaping devices are not permitted in checked luggage. The Transportation Security Administration (TSA) and Federal Aviation Administration (FAA) rules require passengers to take "effective measures" to prevent the accidental activation of the heating element of the device. This is because vaping devices contain lithium-ion batteries, which pose a fire risk if they are damaged, overheat, or short circuit.
If you are travelling with a vaping device, it must be stored in your carry-on luggage or pockets. Each vaping device is limited to a maximum of two lithium-ion spare batteries. These must be individually protected from short-circuiting by keeping them in a battery case or wrapping their terminal ends with insulating tape. The watt-hours rating for lithium batteries cannot exceed 100 Wh.
E-liquids must be stored in containers of 3.4 ounces (100ml) or less to comply with the TSA's 3-1-1 liquids rule for carry-ons. All e-juice bottles should be placed in a single, clear quart-sized bag for screening. Other accessories like replacement coils, O-rings, tools, and chargers can be packed freely in your carry-on luggage.
If you accidentally leave a vaping device in your checked luggage, it will likely be caught during security screening. You may have the option to remove it before your luggage is loaded, but some airports may confiscate the item immediately. To avoid any issues, it is important to plan ahead and pack properly.
