Smooth skies ahead. Both endpoints currently score the same, route health score 100/100. The airports section above carries the live status and delay window at both ends.
Operators schedule morning departures around 07:20 and evening departures around 17:53 from IAH. Earlier flights typically land before destination-airport delays accumulate later in the day; check the OKC delay card to confirm conditions when you'd arrive.
Great-circle distance is 637 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 75–85 min gate-to-gate on this route.
