What time should I arrive for domestic and international flights?

For domestic flights at Hartsfield–Jackson Atlanta International Airport, it is generally recommended that travelers arrive at the airport at least two hours prior to the scheduled departure time. This allows sufficient time for check-in, security screening, and any potential delays. For international flights, it is advisable to arrive at least three hours before the departure time. International travel often involves additional security checks, customs, and immigration procedures, which can take longer than those for domestic flights. Travelers should also consider factors such as the time of day, peak travel periods, and their individual airline’s recommendations, as some airlines may have specific guidelines.
