What does "at risk" mean in the context of travel planning?

In the context of travel planning, "at risk" specifically refers to situations where there is a possibility that travel plans might change or be canceled. This term highlights the uncertainties that can arise in travel, such as unforeseen circumstances, adverse weather conditions, political instability, or changes in health advisories, which could affect a traveler’s itinerary. Therefore, understanding this concept is crucial for both travelers and professionals, as it emphasizes the need for flexibility and the consideration of travel insurance to mitigate potential losses associated with such changes.

The other options do not accurately capture the essence of "at risk" in travel planning. Indicating high levels of customer satisfaction does not relate to the inherent uncertainties in travel arrangements. Describing a trip as fully booked pertains to availability rather than risk. Similarly, a situation where insurance is not needed does not reflect potential changes or cancellations that could make a plan risky.
