IST to IAH questions

Is IST–IAH running on time right now?

Mostly on schedule. The departure side at IST is the weaker end, route health score 78/100. The airports section above carries the live status and delay window at both ends.

Morning or evening flight on IST–IAH?

Operators schedule morning departures around 07:50 from IST. 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 IST to IAH?

Great-circle distance is 10,232 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 752–907 min gate-to-gate on this route.

How often does IST–IAH fly?

Turkish Airlines runs the route with about 9 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
