Firearms must be locked and unloaded in checked baggage
When travelling by air, it is essential to follow the guidelines for the safe storage and transportation of firearms. Firearms must be unloaded and locked in a hard-sided container and transported as checked baggage only. This is a mandatory requirement by the Transportation Security Administration (TSA).
The definition of a loaded firearm, as per 49 CFR 1540.5, includes a live round of ammunition in the chamber, cylinder, or magazine inserted in the firearm. Even if the firearm is unloaded, having access to both the firearm and ammunition is considered the same as having a loaded firearm at a security checkpoint. Therefore, it is crucial to declare firearms and keep them unloaded and locked in checked baggage.
Firearm magazines, bolts, firing pins, and ammunition clips, whether loaded or unloaded, must be secured within a hard-sided case containing the unloaded firearm. Small arms ammunition of up to .75 calibre and shotgun shells can be carried in the same case as the firearm, provided they are securely packaged in a box made of cardboard, wood, plastic, or metal. These boxes must be specifically designed for carrying ammunition and should be declared to the airline.
It is important to note that only the passenger should retain the key or combination to the lock unless TSA personnel request access to ensure compliance with regulations. TSA-approved locks are recommended for convenience and peace of mind, as they can be opened and relocked by TSA agents without causing damage. These locks are easily identifiable by the Red Diamond logo.

Ammunition must be in a locked, hard-sided case
When travelling with firearms and ammunition, it is important to adhere to the regulations set by the Transportation Security Administration (TSA). While the regulations primarily focus on firearms, specific rules are in place for ammunition. One of the key requirements is that ammunition must be stored in a locked, hard-sided case.
This regulation applies to small arms ammunition of up to .75 calibre and shotgun shells of any gauge. The ammunition must be packaged securely in a box made of fibre (such as cardboard), wood, plastic, or metal. The box should be specifically designed to carry ammunition, ensuring it is protected and contained safely. It is worth noting that ammunition cannot be transported loose or in magazines or clips.
The locked, hard-sided case serves multiple purposes. Firstly, it ensures the security of the ammunition, preventing unauthorised access and reducing the risk of theft or tampering. Additionally, it provides protection for the ammunition itself, shielding it from potential damage during transportation. The case also helps facilitate compliance with TSA regulations. By having a designated case, passengers can easily access and present their ammunition for inspection if requested by TSA personnel.
It is important to note that the locked case containing ammunition can be transported in checked baggage. Passengers should declare the presence of ammunition to the airline and ensure that it complies with any quantity limits specified by the airline. This coordination with the airline is crucial to avoid any issues during travel. Passengers should also be prepared for additional screening, as TSA officers have the final decision on whether an item is allowed through the security checkpoint.

Electronics larger than a cell phone must be screened separately
The Transportation Security Administration (TSA) has specific guidelines for travellers carrying electronic devices when passing through airport security. All personal electronic devices larger than a cell phone must be removed from carry-on bags and placed into bins for X-ray screening. This includes items such as laptops, tablets, e-readers, and handheld game consoles. These devices are screened separately from other carry-on items to allow TSA officers to focus on resolving alarms and addressing potential security threats.
It is important to note that this requirement does not extend to all electronic devices. For example, hair dryers, electric shavers, and electric toothbrushes do not need to be removed from carry-on bags for separate screening. Additionally, battery-powered electronics are allowed in carry-on baggage, but hazardous materials are generally prohibited.
To facilitate the screening process and ensure a smooth travel experience, it is recommended that travellers arrive at the airport early and organise their carry-on bags. Keeping bags uncluttered and easily accessible helps TSA officers conduct efficient and thorough screenings.
When it comes to securing checked luggage, travellers are advised to use TSA-approved locks. These locks feature a universal "master" key that allows TSA agents to open and relock luggage without cutting the lock. TSA-approved locks are recognised in 44 countries and over 650 airports, providing travellers with peace of mind and ensuring the security of their belongings.
In summary, travellers passing through airport security with electronic devices must remember that any items larger than a cell phone should be removed from carry-on bags and screened separately. By following this guideline, travellers contribute to enhanced security measures and can expect a more streamlined screening process.
