What does "checked baggage" refer to in aviation?

"Checked baggage" specifically refers to luggage that a passenger hands over to the airline for transport in the aircraft's cargo hold rather than carrying it into the passenger cabin. This process typically involves the passenger checking in their baggage at the airport, where it is tagged and subsequently loaded onto the aircraft.

This distinction is key for several reasons, especially in the context of aviation security and procedures. Checked baggage undergoes different screening processes compared to carry-on items, which remain with the passenger throughout the flight. This is also why there are strict regulations regarding what can be placed in checked baggage, as certain items cannot be transported in the cargo hold for safety and security reasons.

Understanding the definition of checked baggage helps passengers navigate airline policies more effectively, particularly about luggage limits, security protocols, and the procedures at both check-in and baggage claim.
