What does a "layover" refer to in travel terms?

A "layover" refers specifically to a planned stop between flights, during which a traveler waits at an airport before boarding their next flight to their final destination. Layovers can vary in length, from a quick transfer of just a few hours to an overnight stay, and they can occur in the same airport or at a different airport along the travel route. Understanding the concept of a layover is essential for travelers who may need to plan connecting flights, as well as for those looking to maximize their travel experiences by possibly exploring the layover destination if time permits.

In contrast, the other options define different aspects of travel. The final destination of a trip is where the journey concludes, accommodation refers to the places where travelers stay during their trips, and travel restrictions pertain to limitations placed on travel for various reasons, such as health or safety concerns. Each of these elements plays a significant role in travel planning, but they do not capture the essence of what a layover signifies.
