Airport security procedures have become increasingly stringent in the wake of terrorist attacks and threats. The primary goal of aviation security is to prevent harm to passengers, crew, aircraft, and property, as well as to support national security and counter-terrorism policies. To achieve this, airports employ a multi-layered security approach, utilising advanced screening technologies such as body scanners, X-ray machines, and Explosive Detection Systems (EDS). Identity checks, behavioural analysis, and manual checks by security personnel are also crucial components of the security process. Airports also implement comprehensive safety management systems and collaborate with law enforcement to ensure a coordinated response to potential threats. The evolution of security threats demands constant updates to procedures and technologies, with health security measures also becoming a significant focus in recent years.

Check-in and baggage handling
Checking in and handling baggage is a complex process that involves a lot of behind-the-scenes work. It begins with the passenger checking in at the counter, where the check-in agent prints out tags with unique identifiers, including destination codes and routing information, as well as a barcode with a ten-digit number. These tags are attached to each piece of luggage. The barcode allows the baggage-handling system to track the luggage and look up its itinerary.
After check-in, the luggage is placed on a conveyor belt system, which forms the backbone of the Baggage Handling System (BHS). This network of conveyor belts transports the luggage throughout the airport, from the check-in counter to various destinations such as departure gates, transfer areas, or baggage claim. The conveyor belt system is crucial for the efficient movement of luggage within the airport.
The luggage is then routed to the sorting area, where automated sorting machines, like tilt tray sorters, direct each bag based on its encoded flight information. Advanced technology such as barcode scanners and RFID readers ensure accuracy and efficiency in this process. The sorting area is crucial in ensuring that luggage is directed to the correct aircraft for loading.
Once sorted, the luggage undergoes rigorous security screening procedures, including X-ray machines and explosive detection systems, to ensure compliance with aviation security regulations. After clearing security, the luggage is loaded onto carts and transported to the aircraft for stowage in the cargo hold. Ground handlers are responsible for ensuring proper weight distribution and following safety protocols during the loading process.
Upon arrival at the destination airport, the process is reversed. Luggage is unloaded from the aircraft and transferred to the baggage handling system, which directs individual pieces of luggage to the correct carousel in the arrivals area for passenger retrieval. The efficient handling of baggage is critical to ensuring a positive travel experience for passengers and can impact an airport's ability to attract major airline hubs.

Security screening
Passenger Screening:
Passengers are typically screened through metal detectors, walk-through gates, or millimeter wave scanners. Some countries also employ trained individuals who engage passengers in conversations to detect potential threats. This is often coupled with the use of technology. Passengers may be required to remove their shoes, light outer garments, or bulky clothing for inspection. Additionally, passengers with medical or electronic devices may undergo additional screening.
Baggage and Belongings Screening:
Passengers' carry-on baggage and personal belongings are screened using X-ray systems, explosives trace detection, or physical searches. Prohibited items include firearms, ammunition, sporting equipment, and liquids, aerosols, and gels (LAGs) over a certain amount. Some airports are also deploying liquid and bottle scanners to enhance security.
Checked Baggage Screening:
Checked baggage handed over to airlines is screened using advanced technology such as Computed Tomography (CT) systems, explosives detection systems (EDS), and explosives trace detection (ETD). Locks on checked baggage may be cut or opened using universal "master" keys provided to TSA officers to facilitate inspection.
Cargo and Package Screening:
Cargo and packages intended for air transport are also screened using similar methods to ensure they do not contain prohibited items or threats.
Additional Measures:
Airports employ various additional security measures, including police dog services for explosive and drug detection, access control, and video monitoring of checked baggage facilities. The U.S. Department of Homeland Security is actively working to enhance security measures at foreign airports with direct flights to the U.S., which may result in more extensive screening processes.
The specific procedures and technologies used in security screening may vary across airports and countries, and they are subject to change over time as new threats emerge and technology advances.

Boarding
Firstly, it is important to arrive at the airport with plenty of time to spare. Roads to the airport can be congested, and parking facilities may be full, so it is advisable to use public transport. Most flights begin boarding 30-50 minutes before departure, but this can vary depending on your destination and the type of plane. It is recommended that you aim to be at the gate at least 30 minutes before departure, and ideally an hour ahead. Check with your airline for their recommended arrival time.
Once you arrive at the airport, you will need to check in. Online check-in is available 24 hours before departure, and some airlines will send you an email to notify you when this opens. If you have luggage to check in, go to the baggage counter. If you have no luggage to check in, you can proceed straight to security. At security, you will be asked some important questions about what you are carrying, and your hand luggage will be x-rayed for any dangerous goods. You will also need to pass through a metal detector.
After security, you will need to find your gate. This will be printed on your boarding pass. You will need to present your boarding pass at the gate, so keep it handy. Boarding usually ends 15 minutes before departure, and you will not be allowed to board once the doors are closed. If you require special assistance, you can ask to board early.
Finally, you will need to present your boarding pass to the airport staff and board the plane. If you have priority boarding, you will be allowed to board before those in coach. Now you are ready for take-off!

Immigration and customs
Immigration
Immigration is about the people travelling from one country to another. It is sometimes called “passport control” or "border control", depending on the airport. Upon arriving at the desk of an immigration agent, you will likely be asked a variety of questions, such as whether your trip is for business or pleasure, how long you will be in the country, what you do for a living, and what cities you will be visiting during your stay. Immigration officials will review your required passenger travel documents, including your passport, visa, green card, disembarkation card, immunisation documentation, and letters of confirmation or support. Some countries require fingerprints and/or photos of every individual entering the country.
Customs
Customs is about the items that people are carrying with them when crossing international borders. Customs officers may ask about your immigration status to determine whether you have the right to enter the country. They may also ask you to unlock your mobile phone or laptop, although, in the US, citizens cannot be denied entry for refusing to do so. Customs duties apply to certain items like alcohol, tobacco, and gifts. Some goods like meat, produce, and certain plants are prohibited from entering countries like the US without proper approval. Anything you bought, inherited, or received as a gift while travelling may need to be declared at customs. Failing to declare prohibited items could result in fines or penalties, especially for high-value goods.
Preclearance
Customs and Border Protection (CBP) Preclearance involves the strategic stationing of CBP personnel at designated foreign airports to inspect travellers prior to boarding US-bound flights. With Preclearance, travellers can bypass CBP and Transportation Security Administration (TSA) inspections upon arrival in the US and proceed directly to their connecting flight or destination.
