IST to STN questions
Is IST–STN running on time right now?
Smooth skies ahead. Both endpoints currently score the same, route health score 87/100. The airports section above carries the live status and delay window at both ends.
Morning or evening flight on IST–STN?
Operators schedule morning departures around 08:50 from IST. Earlier flights typically land before destination-airport delays accumulate later in the day; check the STN delay card to confirm conditions when you'd arrive.
How long is the flight from IST to STN?
Great-circle distance is 2,456 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 203–241 min gate-to-gate on this route.
How often does IST–STN fly?
Turkish Airlines runs the route with about 10 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
