Cached-fare history: across 5 months, Dec is the cheapest for SF → ROM. Best time to be there: Apr–Jun · Sep–Oct.
Fares bottom out in December around $650 and peak in September near $1,277 — a $627 spread across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13 hours outbound, on a 7-night trip — ticketed under SAS, which on a connecting fare need not operate every leg. At $650 for 10,048 km each way, that works out to about $32 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Across the 18 departure cities we track at a similar distance from Rome, this fare ranks 9th — 1.8× the $356 we hold from Miami. That puts it in the cheaper half of the 45 routes of similar length we watch out of San Francisco, where the middle fare is $796.

SF → ROM, answered.
Is $650 a good price for San Francisco to Rome?
Only slightly. The seasonal median is around $705 round-trip and this fare is 8% under it, about $55. 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 Rome?
Across 5 months of cached-fare history, Dec comes out cheapest on this route. The best months to actually be in Rome are Apr–Jun · Sep–Oct — when those overlap, that's your window.
How far in advance should I book SF → Rome?
We do not publish a number for this, because we cannot measure it yet.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, 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 Rome?
The current cheapest fares involve a connection, ticketed under SAS. 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.
