The recommended arrival time at Atlanta Hartsfield-Jackson International Airport (ATL) is:
- For domestic flights: at least 2 hours before departure.
- For international flights: at least 3 hours before departure.
This allows sufficient time for check-in, security screening, and navigating the large and busy airport. Additional time may be needed during peak travel hours, holidays, or if parking and transportation considerations apply. Programs like TSA PreCheck and CLEAR can help expedite security. It is best to err on the side of arriving earlier to avoid stress and delays at this very busy airport.
