How to read ATL wait coverage
Live minutes
When the source publishes minute values, treat them as the current snapshot, not a guarantee for your future arrival.
Missing or stale data
If live waits are missing, suspended, or outside the freshness window, use posted hours, airport advisories, and peak-window context instead.
Checkpoint counts
Counts reflect what the official source returns for tracked checkpoints; they may not equal every physical lane or every checkpoint serving your gate.

Planning bullets
How locals actually plan ATL
Plan ATL like one big connected airport, not separate terminals.
Domestic and international checkpoints can still feed the wider concourse network once you are screened.
Build in extra post-security transfer time if your gate is far down the concourse system.
If your ride drops you on the wrong side of the airport, your curb-to-checkpoint time can matter more than the TSA line itself.
Checkpoint access
Which checkpoint reaches your gate?
ATL says passengers can access all concourses and gates from any checkpoint, including the domestic and international sides.
