What condition occurs when a passenger misses a connection due to flight delays?

When a passenger misses a connection due to flight delays, the situation is referred to as a misconnection. This term specifically describes the scenario where a traveler is unable to board a subsequent flight because their previous flight arrived late, causing them to miss their scheduled connection.

Understanding this concept is crucial for airline operations and customer service, as it directly impacts passenger experience and necessitates a range of protocols for rebooking and accommodations. Airlines typically have policies in place to manage these situations, ensuring that passengers are rebooked onto alternative flights or provided with necessary assistance.

The other choices represent different contexts in air travel. For instance, an inadmissible passenger refers to individuals who are not allowed entry into a country or territory for various legal reasons, which is unrelated to missed flight connections. A left behind passenger is a term sometimes used but often does not capture the nuances of missed connections due to delays. Interline pertains to agreements between airlines that enable cooperation on ticketing and baggage handling, which is also not directly related to the issue of missing a connection due to delays.
