A layover is a period of time spent at an airport between connecting flights. It occurs when a traveler has to wait for a subsequent flight to reach their final destination. Layovers can vary in length, from a short stop of just an hour to several hours or even overnight, depending on the flight schedule. During a layover, passengers may remain in the airport or leave to explore the surrounding area, depending on the duration and visa requirements. Airports often provide amenities such as lounges, restaurants, and shops to make the wait more comfortable. Travelers should check their flight details to understand the layover duration and any necessary procedures.
