When this route gets cheap.
Fares bottom out in November around $503 and peak in October near $697, 39% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13 hours outbound, on a 5-night trip — ticketed under Gulf Air, which on a connecting fare need not operate every leg. At $517 for 8,642 km each way, that works out to about $30 per 1,000 km flown. That is well under the $44 per 1,000 km that long-haul fares on this board typically run. Across the 20 departure cities we track at a similar distance from Istanbul, this fare ranks 5th — 33% above the $390 from Seoul. It is also the 2nd cheapest of the 26 routes of similar length we watch out of Singapore. The best time to be in Istanbul: Apr–May · Sep–Oct.

Good to know
SIN → IST, answered.
Is $517 a good price for Singapore to Istanbul?
Only slightly. The seasonal median is around $600 round-trip and this fare is 14% under it. 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 Singapore to Istanbul?
Across 6 months of cached-fare history, Nov 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 SIN → 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We do not publish a number for this, because we cannot measure it yet.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, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Singapore to Istanbul?
The current cheapest fares involve a connection, ticketed under Gulf Air. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). 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.
