How to read IAD 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 IAD

Dulles planning is really about the AeroTrain.

West checkpoints (Main Terminal) route onto AeroTrain for Concourses A/B/C/D; plan 5-8 minutes of train time.

Some close-in gates in Concourse A are walkable, but the midfield concourses are AeroTrain-only.

If an international departure is at a midfield gate, a short checkpoint line is not the full picture.

Checkpoint access

Which checkpoint reaches your gate?

At Dulles, the terminal-side checkpoints feed directly to the AeroTrain system just beyond security for the midfield concourses and gates.
