Cached-fare history: across 5 months, Mar is the cheapest for DEL → IST. Best time to be there: Apr–May · Sep–Oct.
Fares bottom out in March around $223 and peak in October near $454 — a $231 spread across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 8.5 hours outbound, on a 6-night trip — ticketed under Kuwait Airways, which on a connecting fare need not operate every leg. At $223 for 4,551 km each way, that works out to about $25 per 1,000 km flown. That is well under the $39 that medium-haul fares on this board typically run. It is also the cheapest of the 25 routes of similar length we watch out of Delhi.

How far in advance should I book DEL → 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We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Mar comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Delhi to Istanbul?
The current cheapest fares involve a connection, ticketed under Kuwait Airways. 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.
