Is $133 a good price for Copenhagen to Istanbul?
Only slightly. The seasonal median is around $160 round-trip and this fare is 17% under it, about $27. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Copenhagen to Istanbul?
Across 7 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Istanbul are Apr–May · Sep–Oct — when those overlap, that's your window.
How far in advance should I book CPH → Istanbul?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 7 months of cached fares, Oct comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Copenhagen to Istanbul?
Yes — the current board includes nonstop fares (Ajet). The outbound leg runs around 3.5 hours.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
