If you are calling the Airport Authority lost and found at 336-665-5655 it is monitored by a police officer they work a 5-day schedule so if you contact them on one of their days off it could be 48 hours. You can also contact the TSA for lost items at 336-358-4444.
There is no definite answer to your question. Usually with 24-48 hours but could vary depending on circumstances.
