Cached-fare history: across 6 months, Mar is the cheapest for CHI → MAD. Best time to be there: Apr–Jun · Sep–Oct.
Fares bottom out in March around $406 and peak in December near $1,034 — a $628 spread across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 9.5 hours outbound, on a 8-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $406 for 6,725 km each way, that works out to about $30 per 1,000 km flown. That is well under the $44 that long-haul fares on this board typically run. Across the 12 departure cities we track at a similar distance from Madrid, this fare ranks 3rd — 38% above the $295 from Dubai. It is also the 3rd cheapest of the 28 routes of similar length we watch out of Chicago.

How far in advance should I book CHI → Madrid?
We do not publish a number for this, because we cannot measure it yet.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, 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 Chicago to Madrid?
The current cheapest fares involve a connection, ticketed under United. 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.
