What describes the hub-and-spoke travel model?

The hub-and-spoke travel model effectively describes a system where a central hub is established, with multiple spokes extending out to various destinations. This model is commonly utilized in airline traffic, where flights are routed through a central hub before reaching their final destinations.

Choice B captures the essence of this model by illustrating how travelers can use the central hub as a base, allowing for accommodations at that location while enabling them to take day trips to surrounding destinations. This flexibility is a key differentiator for travelers, as it provides the opportunity to explore multiple areas efficiently, without the need for constant repacking and moving between accommodations.

The other options do not align with the foundational concept of the hub-and-spoke model. Options highlighting direct flights, a focus on cruises, or ticketing inflexibility do not accurately reflect the operational strategy or the benefits that the hub-and-spoke system provides.
