What is the term for baggage that the airline takes complete control of during transport?

The term for baggage that the airline takes complete control of during transport is checked baggage. When passengers check their bags at the airport, these items are tagged and placed in the care of the airline, which then manages their handling throughout the flight. Checked baggage is transported in the cargo hold of the aircraft, separate from the passenger cabin, and is retrieved upon arrival at the passenger's destination. This process ensures that the baggage is secured and managed properly while the airline maintains responsibility for it during the journey.

In contrast, cabin or hand-carried baggage refers to the items that passengers keep with them in the aircraft's cabin, thus remaining under the passenger's control throughout the flight. Standby baggage is not an official term used in airline operations and could refer to items waiting for space on flights, while crew baggage pertains to items personal to the flight crew that may be handled differently.
