Cached-fare history: across 6 months, Dec is the cheapest for SF → IST. Best time to be there: Apr–May · Sep–Oct.
Fares on this route stay within about $112 across the 6 months we track — season matters less here than timing the drop. The cheapest itinerary we are tracking makes one stop and takes about 14 hours outbound, on a 18-night trip — ticketed under Lufthansa, which on a connecting fare need not operate every leg. At $866 for 10,785 km each way, that works out to about $40 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Across the 15 departure cities we track at a similar distance from Istanbul, this fare ranks 12th — 2.3× the $381 we hold from Los Angeles. For context, the middle fare among the 52 routes of similar length we watch out of San Francisco is $813.

SF → IST, answered.
Is $866 a good price for San Francisco to Istanbul?
Only slightly. The seasonal median is around $890 round-trip and this fare is 3% under it, about $24. 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 San Francisco to Istanbul?
Across 6 months of cached-fare history, Dec 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 SF → 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We do not publish a number for this, because we cannot measure it yet.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 6 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 San Francisco to Istanbul?
The current cheapest fares involve a connection, ticketed under Lufthansa. 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.
