Airports' Scanning Secrets: How Checked Luggage Is Inspected

The process of scanning checked luggage at airports involves several steps to ensure security and identify potential threats. After check-in, luggage is typically placed on a conveyor belt and screened using X-ray machines or CT scanners. These scans allow for the examination of each bag's contents, helping to detect prohibited items and security risks. In some cases, advanced imaging technology and manual inspections by security personnel may be utilized for further scrutiny. Additionally, airports may employ chemical sniffers to enhance the screening process. The primary objective of these procedures is to ensure the safety of passengers and aircraft by identifying and addressing potential hazards, such as explosives and other dangerous items.

Scanning and screening procedures

Checked luggage is scanned for the same reasons as hand luggage: to check for prohibited items and other threats to transportation security. Scanning procedures for checked luggage typically involve X-ray machines, and sometimes additional technology such as CT scanners and chemical sniffers. TSA officers are primarily looking for explosives, but they are also trained to identify other prohibited items. If a bag is deemed suspicious or requires further examination, it may be inspected by hand by a member of security personnel. If a locked bag needs to be inspected, officers will attempt to use a master key to open it, but if this is not possible, they may have to use other means of opening it, and will then reseal the bag securely.

At some airports, checked luggage is taken to a secure area known as the "checked baggage zone" or "baggage zone", where it is screened away from public view. This area is highly secure, and only authorised personnel are allowed access. The screening process involves a series of conveyor belts, with bags that are cleared being moved along with a diverter, and those requiring further inspection being sent for additional screening. If a bag is searched, a note will be left for the owner to explain that it has been inspected and why.

In addition to the screening of luggage, the TSA also operates a risk-based passenger pre-screening program called Secure Flight. This program identifies low and high-risk passengers before they arrive at the airport by matching their names against trusted traveller lists and watchlists. Passengers flying into the U.S. may experience a more extensive screening process, including additional screening of personal electronic devices. It is recommended that passengers flying into the U.S. arrive early at the airport to allow enough time for this screening process.

Locks and security

TSA-approved locks are identifiable by their distinctive red diamond logo, the Travel Sentry Red Diamond, which is recognised in 44 countries and over 650 airports. These locks provide convenience and peace of mind, playing a crucial role in maintaining the safety and integrity of checked luggage. They prevent unauthorised access, minimising the risk of theft or tampering.

However, it is important to note that even with TSA locks, there is no guarantee that belongings will be completely safe. Some individuals can still break into locked luggage, and thieves may simply slice through soft-sided bags. Therefore, travellers are advised to keep valuable items in their carry-on luggage, as the TSA typically does not reimburse for stolen items from checked bags, and airlines are usually not liable for the loss of expensive items.

Additionally, travellers can consider alternative security measures such as zip ties, which are less expensive and can be clipped off by TSA agents if needed. Some travellers also opt for plastic wrapping services offered at airports, which can prevent theft and baggage damage. Overall, while locks and security measures can enhance the protection of checked luggage, it is always advisable to remain vigilant and take necessary precautions to safeguard valuable possessions during air travel.

Baggage drop-off and check-in

The bag drop-off and check-in process can vary depending on the airport and airline. It is recommended to arrive at the airport 1-1.5 hours before a domestic flight and 2-3 hours before an international flight to allow sufficient time for check-in, security, and navigating to the gate. Some airlines may have specific time frames for bag drop-off, such as opening 2 hours before departure and closing 1 hour before. It is important to check with the specific airline or airport for their guidelines.

Several airlines allow passengers to check in their bags hours or even days before their departure, which can simplify the airport experience. Online check-in options are also available with many airlines, allowing passengers to check bags and print boarding passes from the convenience of their homes.

When dropping off checked bags, passengers will need to go to the designated bag drop counters, which can vary by airport and airline. It is important to keep the baggage claim tag safe, as it will be needed to pick up the bags at the destination. Passengers should also be aware of any prohibited items and ensure their bags comply with the airline's guidelines.

After dropping off checked bags, passengers will head to the security checkpoint with their carry-on items. At the security checkpoint, passengers may be asked to remove personal electronic devices larger than a cell phone, such as laptops and tablets, for separate screening. Certain airports may also require the removal of light outer garments or bulky clothing for additional screening if the passenger is unable or unwilling to remove them.

Checked luggage typically undergoes multiple scans to ensure the safety and security of air travel. These scans are performed by the Transportation Security Administration (TSA) in the United States, and similar agencies in other countries, to prevent prohibited items and potential threats from entering the secure areas of the airport.

Connecting flights

When it comes to connecting flights, the process for scanning checked luggage varies depending on the airport and the country where the layover is. In most cases, if you have a domestic layover, your checked luggage will be tagged, transported, and dealt with by the airline to ensure it reaches your final destination. This means that your luggage will be sent directly from one plane to another without undergoing additional security scans.

However, if you have an international layover, the process may differ. Some airports or connecting routes may require your bags to be scanned again in between connecting flights. Additionally, if you are flying from outside the US or Canada and have a layover in one of these countries, you will typically need to collect and recheck your luggage. On the other hand, if your connecting flight is within the same airport or a different one in the same country, your luggage might be transferred to your final destination without the need to recheck it.

It is important to note that the security scan for checked luggage is similar to that of carry-on bags and passengers. X-ray scanners, CT scanners, and chemical sniffers are used to detect metallic and non-metallic objects, organic materials, and even small amounts of paper or money. If any suspicious items are detected, security personnel may conduct a physical inspection of the bag.

To ensure a smooth transition during your connecting flights, it is recommended to allow for sufficient time during layovers and to confirm with the airlines involved in your journey if you need to collect and recheck your luggage at any point.

Prohibited items

When it comes to prohibited items in checked luggage, there are several categories of items that are restricted for safety and security reasons. Firstly, electronic devices and batteries are highly regulated. Portable chargers or power banks for smartphones and other devices are prohibited from being checked in, and must be carried in carry-on luggage. Similarly, spare batteries, such as lithium or lithium-ion batteries, must be individually protected to prevent short circuits and are subject to certain wattage restrictions. While laptops and tablets are permitted in checked luggage, it is generally recommended to keep them in carry-on baggage.

Flammable and explosive substances are also prohibited in checked luggage. This includes items like fireworks, dynamite, gasoline, and other explosive or flammable devices. Small cigarette lighters and safety matches are allowed on one's person but not in checked baggage, and some countries prohibit these items altogether. Additionally, chemical and toxic substances that pose a risk to health or property, such as disabling sprays (mace, pepper spray, tear gas), acids, poisons, and radioactive materials, are forbidden.

Weapons and firearms are generally prohibited in checked luggage, although there may be exceptions for those with the required permits and licenses for shooting and hunting purposes. Sharp objects, such as scissors and knives, and items that could be used as weapons, like golf clubs or blunt objects, are typically not allowed in carry-on baggage and must be checked in.

Other prohibited items include magnetized materials, infectious agents, items emitting strong odours, and alcoholic beverages exceeding 70% by volume, which are considered flammable. Powder-like substances over 12 oz or 350 mL should also be placed in checked baggage. It is important to note that local rules may vary, and certain countries or airlines may have specific restrictions. For example, when travelling to Kenya, Tanzania, or Rwanda, plastic bags are not allowed.
