Cached-fare history: across 7 months, Dec is the cheapest for IST → DEL. Best time to be there: Oct–Mar.
Fares bottom out in December around $314 and peak in November near $413 — a $99 spread across the 7 months we track. The cheapest itinerary we are tracking makes one stop and takes about 7 hours outbound, on a 32-night trip — ticketed under Azerbaijan Airlines, which on a connecting fare need not operate every leg. At $314 for 4,551 km each way, that works out to about $34 per 1,000 km flown. That is below the $39 typical of medium-haul fares here. Across the 12 departure cities we track at a similar distance from Delhi, this fare ranks 2nd — 11% above the $283 from Singapore.

Is $314 a good price for Istanbul to Delhi?
Only slightly. The seasonal median is around $330 round-trip and this fare is 5% under it, about $16. 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 Istanbul to Delhi?
Across 7 months of cached-fare history, Dec comes out cheapest on this route. The best months to actually be in Delhi are Oct–Mar — when those overlap, that's your window.
How far in advance should I book IST → Delhi?
We do not publish a number for this, because we cannot measure it yet.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, Dec comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Istanbul to Delhi?
The current cheapest fares involve a connection, ticketed under Azerbaijan Airlines. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
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.
