How delays work at ATL

A ground stop holds flights bound for ATL at their origin airports. A ground delay program spaces arrivals out so the airport is not overloaded. Departure and arrival delay messages describe the average wait the FAA expects. None of these tell you whether your own flight is late, so always check your airline as well.

Local tips

  • Allow extra time if you need to change between the Domestic and International terminals; they are separate buildings.
  • If your layover is short, check the gate before you leave the arrival gate. Walking to a far concourse can be slower than the train when it is busy.
  • Summer afternoon thunderstorms are a frequent delay driver at ATL; check the on-time performance table on this page and prefer morning departures when you can.
