Cheap flights from Kos to Istanbul

The weeks on either side of December can be close in price to the cheapest month itself, so check the price calendar before you settle on dates. December is the cheapest month on this route, but school holidays and the year-end period can still push fares up on the peak days. Midweek departures are often less pressured than weekend ones, and the listed months with prices include October, November, February, April, May, June and July as well as December, so you can shift the trip if your dates are flexible.

The list mixes carriers that tend to price a low base fare with extras added later and carriers that include more in one ticket, so read the fare rules before you compare totals. None of the listed options is nonstop between Greece and Turkey, and connection times, baggage allowances and seat choices differ by airline and date. Sky Express, Aegean Airlines, Olympic Air, Eurowings Discover, Luxair and Finnair all appear on this route, so check which carrier your ticket names and whether that connection is protected on one ticket.

Istanbul Airport is the larger gateway and Sabiha Gokcen is the smaller second airport, so expect longer walks and queues at the first and a quicker exit at the second. The two airports sit on different sides of the city, and traffic into the centre can be heavy at peak times, so allow extra time whichever you use. Metro, bus, taxi and airport shuttle services link both airports to the centre, and the right choice depends on where you are staying and which side of the city you need.
