Air conditioning works overnight by continuously circulating and cooling the air in the room. The system draws in warm air from the room, passes it over a cold evaporator coil to remove heat and moisture, and then recirculates the cooled air back into the room. The process is controlled by a thermostat, which monitors the temperature and adjusts the system to maintain the desired level of cooling throughout the night. This allows for a comfortable and consistent temperature while sleeping. **

During a layover, passengers may have the opportunity to explore the airport or city before continuing their journey. **
