What is a "no-show" passenger?

A "no-show" passenger is specifically defined as someone who does not board the flight and fails to notify the airline of their absence. This designation is important because it impacts the airline's operations and passenger management strategies, including seat availability and revenue considerations. When a passenger is categorized as a no-show, the airline may release their seat for other travelers or impose penalties regarding fare refunds, depending on the ticket policies. The inability of such passengers to communicate with the airline is significant since it disrupts efficient seat allocation and overall planning for the flight. Understanding this definition is crucial for inflight service staff as it directly relates to customer service practices and ticket regulations.
