IST to STR questions
Is IST–STR running on time right now?
Some delays possible. The departure side at IST is the weaker end, route health score 65/100. The airports section above carries the live status and delay window at both ends.
Morning or evening flight on IST–STR?
Operators schedule morning departures around 07:50 and evening departures around 19:05 from IST. Earlier flights typically land before destination-airport delays accumulate later in the day; check the STR delay card to confirm conditions when you'd arrive.
How long is the flight from IST to STR?
Great-circle distance is 1,736 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 153–179 min gate-to-gate on this route.
How often does IST–STR fly?
Turkish Airlines runs the route with about 26 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
