SAT to IAH questions

Is SAT–IAH running on time right now?

Significant delay risk. The arrival side at IAH is the weaker end, route health score 50/100. The airports section above carries the live status and delay window at both ends.

Morning or evening flight on SAT–IAH?

Operators schedule morning departures around 00:30 from SAT. Earlier flights typically land before destination-airport delays accumulate later in the day; check the IAH delay card to confirm conditions when you'd arrive.

How long is the flight from SAT to IAH?

Great-circle distance is 306 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 52–56 min gate-to-gate on this route.

How often does SAT–IAH fly?

United Airlines runs the route with about 50 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
