Tips for Connecting at ATL
→Book both legs on the same ticket. If you miss your connection, the airline must rebook you at no charge. Separate tickets mean you're on your own.
→Choose morning flights for your first leg. Flights before 8 AM are delayed significantly less than afternoon flights.
→Check the terminal layout. If your arrival and departure gates are in different terminals at ATL, add extra time for the transfer.
→Avoid checking bags on tight connections. Carry-on only gives you maximum flexibility if you need to switch flights.
