Morning or evening flight on IST–KFS?
Operators schedule morning departures around 08:20 and evening departures around 19:25 from IST. Earlier flights typically land before destination-airport delays accumulate later in the day; check the KFS delay card to confirm conditions when you'd arrive.

Great-circle distance is 421 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 60–66 min gate-to-gate on this route.
