Stopover in Houston: what to do and when to leave
IAH combines extensive terminals, immigration and a cautious return through security. Downtown and Museum District are the most concentrated exits; avoid crossing Houston with a short layover.
With less than 11 hours, stay at IAH. From 12–14 hours Downtown can fit if you can enter the United States, the baggage is checked through to the final destination and you reserve three hours to return.
