It is a scheduled break in the journey that can vary in length, ranging from a few hours to even a day or more. Layovers are typically necessary when there are no direct flights available to reach the final destination, or when connecting flights are more cost-effective than a direct flight. During a layover, passengers may have the opportunity to explore the airport or city before continuing their journey. **
