If my flight leaves at time: 8:00am; what time am I to be at the airport?

Before 2 hours

Get to the airport 2 hours before. The security lines are very long. I would suggest being there no later than 5:30 if you are going through the general boarding lines.

No later then 6am. ATL airport is very Busy, crowed

Depends on the day , but I would get there 2 hours before my flight. You have to check in , check bags , clear security. Then find what gate you are departing from . enjoy your trip. Be careful and stay safe

You should be there between 5:30 -6 it's a very big airport and it takes time to get thru security, check and getting to your gate. Better to be there before time than to be rushing and risk missing your flight.
