You've likely checked a bag on countless flights, rarely thinking about it as it reliably appears on the carousel. But have you ever stopped to wonder what truly happens in between or how airlines manage to keep tabs on so much luggage? Despite recent reports showing over 99% of bags arrive without issues, suggesting a highly sophisticated system, there's a complex process at play. Let's take a behind-the-scenes look at the journey your bag takes after you check it at the airport.

Kicking off the bag check
During check-in, either an airport customer service agent or a self-service kiosk will help you print and attach a luggage tag to your bag. This tag holds crucial details like your name, your airline and flight number, and the airport code for your destination.
These tags also incorporate barcodes, allowing employees and automated systems to scan them for efficient sorting and tracking. The barcodes specifically contain a baggage tag issuer code (BTIC), a baggage type code, and your bag's unique identification number. Once the tag is secured, your luggage starts its journey down the conveyor belt for security screening, sorting, and eventually loading onto the aircraft.
Time for security checks
Behind the scenes, the initial step for your checked luggage is typically a thorough security screening. Your bag passes through either an X-ray machine or a CT scanner, and most bags are quickly processed and sent on their way.
In some instances, however, security agents might pull your bag aside for a physical inspection. Most of the time, this is simply an extra precaution; once the agents have examined the bag, they'll re-zip it and send it off for sorting.
Occasionally, though, security officers might discover a prohibited item, which they'll either confiscate or report to airline representatives to discuss potential consequences with you. If a physical inspection occurs, TSA personnel will insert a notice into your luggage to inform you that a more detailed screening took place.
Luggage sorting
Once your luggage successfully clears the security inspection, the next step is its precise sorting for the correct flight. Generally, an automated computer system scans the luggage tag to determine its destination, then directs the bag onto the appropriate conveyor belt.
At busier airports, these conveyor belt networks can be vast. For example, Toronto Pearson International Airport (YYZ) – Canada's busiest – features over 18 miles of conveyor belts, which in 2019 handled more than 100,000 bags daily. Both human staff and security cameras oversee this system, ensuring bags move correctly. Should your bag fall off or encounter another issue, its tag will be rescanned to retrieve its information, and the luggage will then be rerouted to its intended destination.
If your flight is still several hours away, your luggage might be held in a secure location until it's time for it to be loaded onto the plane. Rest assured, employees are trained to diligently monitor the luggage and security cameras, ensuring all bags efficiently reach their designated departure points.

Plane loading and unloading
After the bags have been accurately sorted, baggage handlers collect the prepared luggage, load it onto a baggage cart, and transport it across the tarmac to the correct aircraft for loading before its scheduled departure.
At the journey's end, a different team of baggage handlers unloads the luggage from the arriving aircraft at the terminal and transfers it to the airport's baggage sorting system. Inside this facility, the crew places all the luggage onto a conveyor belt that carries it directly to the baggage claim area. Each bag then emerges from a chute onto the appropriate carousel, where passengers can retrieve it – hopefully within a reasonable timeframe – and continue their travels.
According to a report from The New York Times, it typically takes anywhere from 15 to 45 minutes for bags to reach the baggage claim area after an airplane arrives at the gate. This timeframe is influenced by factors like the airport's size and the modernity of its sorting systems. Some airlines, such as Delta and Alaska, even guarantee customers will receive their bags in 20 minutes or less. If it takes longer, passengers may be eligible to submit a claim for compensation in the form of rewards miles or a voucher.
Delay possibilities
While the checked baggage process often proceeds smoothly, several common mishaps can lead to delays. Staffing shortages, for instance, can result in longer wait times, as each crew member is limited in the number of bags they can handle simultaneously. In addition, extreme weather conditions can prevent crew members from performing their duties; they cannot, for example, transport luggage onto the tarmac during lightning storms or torrential downpours.
Another potential issue? A traffic jam within the luggage conveyor belt system. Loose metal pieces or stray strings can become entangled in the sorting mechanisms, causing bags to get stuck and potentially creating large pile-ups.
However, passengers can take simple precautions at home to minimize the chances of this happening. Toronto's Pearson Airport advises ensuring that no loose straps or other features are dangling from your bag, as these can easily get caught in the machinery and cause delays.
What to do if your luggage goes missing?
Though it's a rare occurrence, if your checked luggage does happen to be delayed or lost, there are several immediate steps you can take to track down your bag.
Before heading to the customer service counter, first try checking the airline's app. Several airlines – including Southwest, American, Delta, and United – now offer live baggage tracking directly through their apps, providing real-time updates on your bag's journey. Alternatively, you might already be ahead of the curve by having placed an Apple AirTag or a similar tracking device inside your luggage – something we highly recommend you always do when checking a bag.
Even after checking the app or speaking with an airline representative, either at the airport or by phone, you might not immediately locate your bag. In such cases, you may need to file a claim before leaving the airport. Be sure to obtain a claim number and provide your contact information, along with your hotel or residence address, so you can monitor the airline's progress in finding your luggage and ensure prompt delivery once it's located.
If you still haven't received an update the following day, you might be eligible to file a claim for compensation due to delayed or missing luggage. For most domestic flights, a claim can typically be filed in as little as 24 hours, while international travel usually requires a week. You can also contact the TSA directly for additional information, as they can investigate the claim and provide you with relevant details should any issues arise.
