Checking bags at the airport is a standard procedure that helps ensure aviation safety. After passengers hand over their checked baggage at designated counters, it is tagged and transported via conveyor belts to a central sorting area. Most airports employ Explosive Detection Systems (EDS) that use X-rays and CT scans to screen baggage for potential threats. If a bag requires further inspection, a Transportation Security Officer (TSO) reviews the scan and may physically inspect the bag's contents. This multi-layered security approach, involving collaboration between the TSA, intelligence agencies, and law enforcement, aims to safeguard passengers, crew, and aircraft from evolving threats.

Checking in bags at the airport
Before Arriving at the Airport
Security measures for air travel begin long before you arrive at the airport. The Transportation Security Administration (TSA) works closely with intelligence and law enforcement agencies to gather information and adapt security procedures based on evolving threats. As a result, you may notice changes in their procedures from time to time. It is recommended that you arrive at the airport early to allow enough time for the screening process.
Checking In
When checking in your bags, you can save time and money by paying for your checked bags online or through the airline's app before arriving at the airport. Some airlines, such as American Airlines, offer the option to check up to three bags per person in advance. If you have more than three bags, you will need to add them at the airport, and additional charges for oversized or overweight bags may apply.
Prohibited Items
It is important to familiarize yourself with the restrictions on items allowed in checked baggage. Most hazardous materials are prohibited in both carry-on and checked baggage. For your convenience, it is recommended to place powder-like substances over 12 oz (350 mL) in your checked bags, as powders in carry-on baggage may require secondary screening and could be prohibited from the aircraft cabin.
Security Screening
After checking in your bags, they will go through security screening. TSA employs both visible and unseen measures to ensure safe travel. Individual airports are responsible for monitoring checked baggage facilities, and methods may include CCTV. If your property is lost or damaged during the screening process, you can file a claim with TSA. TSA has also implemented universal "master" keys to inspect locked bags without cutting certain branded locks.
Picking Up Your Bags
Once you arrive at your destination, you will need to pick up your checked bags at the baggage claim area. If your property is lost or damaged during transport to the plane or baggage claim, contact your airline. It is important to report any suspicious activities or unattended bags to local law enforcement as part of TSA's layered approach to security.

Security screening
When checking a bag at the airport, passengers typically bring their luggage to their airline's counter or kiosk before proceeding through security. Some airports have separate counters for baggage drop-off, while others handle it at the regular check-in counter. Once checked in, bags are tagged and transported via conveyor belts to a central sorting area. Here, automated systems scan the tags to route the bags to their respective flights.
Before loading a bag onto an aircraft, it undergoes security screening. Most airports utilize Explosive Detection Systems (EDS) that employ X-rays and CT scans to create a 3D image of the bag's contents. If the scan raises no concerns, the bag is cleared for loading. However, if something requires further examination, a Transportation Security Officer (TSO) reviews the scan. Bags requiring physical inspection are moved to a secure area, where a TSO may open and manually check the contents. If a bag is locked and cannot be opened with a TSA key, the lock may be cut to facilitate inspection.
Passengers play a crucial role in the security screening process. It is recommended to arrive at the airport early to allow sufficient time for screening. Certain items, such as hazardous materials, are prohibited from both carry-on and checked baggage. Powders in carry-on bags may trigger secondary screening, and lithium batteries are not permitted in checked luggage. Passengers are encouraged to report any unattended bags or suspicious activities to law enforcement, as part of TSA's layered security approach.

Baggage fees
Most airlines allow passengers to check bags weighing up to 50 pounds, but some, like Spirit and Frontier, cap the weight at 40 pounds. Some airlines also have different baggage policies for specific destinations, so it is worth checking before travelling. For example, American Airlines offers free checked bags for all customers travelling to Argentina, Brazil, China, India, Japan, and Australia or New Zealand, where bags can weigh up to 70 pounds.
Some airlines, such as American Airlines, allow passengers to pay for checked bags online before arriving at the airport. This can be done through the airline's website or mobile app. However, additional bags may need to be added at the airport, and oversize, overweight, and excess bag charges may apply.
It is recommended to arrive at the airport early to allow enough time for the check-in and screening processes. Some airlines have separate counters for baggage drop-off, while others use the regular check-in counter. If you already have your ticket, you can usually print a sticker at a kiosk and drop off your bag right there.

Baggage claim
Checking in baggage at the airport is a straightforward process, but it's always good to be prepared. Firstly, it is recommended to arrive at the airport early to allow enough time for the screening process and to avoid long queues at the check-in counter. Some airlines have a separate counter for baggage drop-off, while others do this at the regular check-in counter. If you have your boarding pass, look for a counter that says "Baggage Drop Off".
If you are checking in more than 3 bags per person, you will need to add the additional bags at the airport, where you may be subject to oversize, overweight, and excess bag charges. These charges are calculated per person, each way, and are based on standard bag sizes. You can pay for your bags online ahead of time, or at the airport.
Once your bag is tagged at check-in, it is loaded onto a series of conveyor belts that move it through the airport to a central sorting area. Here, automated systems scan the tag and direct it towards the right flight. Before reaching the plane, your bag goes through security screening, which may include X-rays and CT scans to inspect the contents. If the scan detects something suspicious, a Transportation Security Officer (TSO) will review the scan and decide if the bag needs to be opened.
To ensure a smooth baggage claim process, it is recommended to tie a bright ribbon to your bag or use a unique colour so that it is easily identifiable. If your bag does not arrive at your destination, you should file a baggage claim and provide as much detail as possible to the airline staff. Most bags are located and returned quickly, especially if they are properly tagged.

Connecting flights
When you check in a bag at the airport, you receive a luggage receipt with details of your connecting flights. The bag is then screened for prohibited items and sorted, before being loaded onto a cart or cargo container and taken to the plane. The barcodes on the tags are checked to ensure the bags make it to the correct location.
If you are travelling on a single ticket with the same airline within the US, you do not need to recheck your baggage. However, if you are entering the US from abroad, you must go through customs, which involves having your luggage screened. If you do not obtain your baggage after your international flight, it will not be sent to your final destination. The exception to this rule is if you are travelling from an airport that offers CBP preclearance, in which case travellers go through customs at their departure point. There are 15 airports that offer CBP preclearance across Ireland, Aruba, Bermuda, the United Arab Emirates, the Bahamas, and Canada.
If you have a connecting flight within the US after an international flight, you will need to re-check your bags. It is recommended that you ask the person processing your suitcases if they will be checked through to your final destination and double-check the tag attached to your bag. If you have a tight connection (90 minutes or less), there is a higher chance that your checked luggage will not make it onto your next flight if your first flight is delayed.
