Morning or evening flight on IST–BIO?

Operators schedule morning departures around 07:50 from IST. Earlier flights typically land before destination-airport delays accumulate later in the day; check the BIO delay card to confirm conditions when you'd arrive.

How long is the flight from IST to BIO?

Great-circle distance is 2,599 km. With typical jet cruise speed plus taxi, climb and descent, expect roughly 213–253 min gate-to-gate on this route.
