How to read IAH 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 IAH

IAH's Skyway gives you post-security flexibility across all five terminals.

All terminals A-E are linked post-security by the Skyway people-mover; choose the fastest practical checkpoint.

International arrivals (Terminal D/E) still involve separate passport processing on the return trip.

Skyway movement between terminals costs real minutes, so do not stretch a 'short line' into a guaranteed on-time.

Checkpoint access

Which checkpoint reaches your gate?

IAH says all five terminals are connected post-security by the Skyway people-mover.
