When this route gets cheap.
Fares bottom out in February around $509 and peak in October near $763, 50% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 10.5 hours outbound, on a 8-night trip — ticketed under SAS, which on a connecting fare need not operate every leg. At $509 for 6,651 km each way, that works out to about $38 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 11 departure cities we track at a similar distance from Paris, this fare ranks 5th — 2.3× the $220 we hold from Abu Dhabi. It is also the 3rd cheapest of the 27 routes of similar length we watch out of Chicago. The best time to be in Paris: Apr–Jun · Sep–Oct.

Good to know
CHI → PAR, answered.
Is $509 a good price for Chicago to Paris?
Yes — the seasonal median for this route is around $680 round-trip. At $509 you're 25% below that, which we rate good for this route.
What is the cheapest month to fly from Chicago to Paris?
Across 5 months of cached-fare history, Feb comes out cheapest on this route. The best months to actually be in Paris are Apr–Jun · Sep–Oct — when those overlap, that's your window.
How far in advance should I book CHI → Paris?
We do not publish a number for this, because we cannot measure it yet.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, Feb comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Chicago to Paris?
The current cheapest fares involve a connection, ticketed under SAS. 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.
