IST to BSL questions

Is IST–BSL running on time right now?

High disruption likely. The departure side at IST is the weaker end, route health score 6/100. The airports section above carries the live status and delay window at both ends.

Morning or evening flight on IST–BSL?

Operators schedule morning departures around 07:40 from IST. Earlier flights typically land before destination-airport delays accumulate later in the day; check the BSL delay card to confirm conditions when you'd arrive.

How long is the flight from IST to BSL?

Great-circle distance is 1,818 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 158–186 min gate-to-gate on this route.

How often does IST–BSL fly?

Turkish Airlines runs the route with about 14 flights a week (daily). Since one carrier owns the route, a single disruption tends to ripple through the day.
