GRU to IST questions
Is GRU–IST running on time right now?
Smooth skies ahead. The departure side at GRU is the weaker end, route health score 88/100. The airports section above carries the live status and delay window at both ends.
Morning or evening flight on GRU–IST?
Operators schedule morning departures around 04:10 from GRU. Earlier flights typically land before destination-airport delays accumulate later in the day; check the IST delay card to confirm conditions when you'd arrive.
How long is the flight from GRU to IST?
Great-circle distance is 10,559 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 775–935 min gate-to-gate on this route.
How often does GRU–IST 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.
