What can cause a "Misconnect" for a traveler?

A "misconnect" occurs when a traveler is unable to make their connecting flight due to various reasons, primarily related to scheduling and operational issues. Flight delays caused by irregular operations are a significant factor in this scenario. When a flight is delayed, it can disrupt a traveler's itinerary, causing them to miss their subsequent connecting flights if they do not have enough time to transfer from one flight to the next. This could entail lost time at the airport, additional stress, and potential rebooking needs, which all stem from the initial delay.

In contrast, although personal cancellations, changes in destination, and booking errors can lead to travel disruptions, they don't fit the traditional definition of a "misconnect" since they don't involve a failure to connect due to timing issues between flights. Instead, they relate more to traveler decisions or changes that might not align with airline scheduling. Thus, the fundamental link to "misconnecting" lies in operational disturbances that directly impact flight schedules, making delays due to irregular operations the correct answer in this context.
