How to find cheap flights from Madrid to Chicago

Book 8–12 weeks out. Standard transatlantic curve: the fare bottom sits two to three months before departure.
Fly midweek, both ways. Tuesday–Thursday transatlantic departures routinely cost €80–150 less than weekend ones.
Price the one-stops. Dublin, London, Amsterdam, Frankfurt, Zurich and Reykjavik are common connection points, and a well-timed stop beats the nonstop price more often than you’d think.
Travel the transatlantic low season. Late January–February and early November are the fare floor; June–August and Christmas are the ceiling.

Airports: MAD and ORD

You depart from Adolfo Suárez Madrid–Barajas (MAD) — most US-bound flights leave from Terminal 4 or Terminal 1 depending on carrier. Barajas is enormous: confirm your terminal before you leave home. The Cercanías C-1 train or Metro Line 8 gets you there from the center in 30–40 minutes.

You arrive at Chicago O’Hare (ORD), one of the world’s busiest airports. International arrivals clear immigration at Terminal 5 — budget 60–90 minutes at peak times. The CTA Blue Line runs from O’Hare to downtown in about 45 minutes for around $5, one of the best airport-to-city deals in America. Midway (MDW) exists but has no Madrid flights.

Airlines flying Madrid–Chicago

Nonstop (about 9h–9h30 westbound): Iberia and American both fly MAD–ORD nonstop, coordinated as partners. That dual presence keeps nonstop fares competitive.
One stop in Europe: Aer Lingus via Dublin (with US preclearance in Dublin — you land stateside as a domestic passenger), Lufthansa via Frankfurt, KLM via Amsterdam, Swiss via Zurich, British Airways via London, Icelandair via Reykjavik.
One stop in the US: United via Newark or Washington connecting into O’Hare.

The Dublin preclearance trick is worth knowing: you clear US immigration in Ireland, so your Chicago arrival is fast and connections are stress-free. Aer Lingus fares via Dublin are frequently among the lowest on this route.

Best time to fly Madrid to Chicago

Cheapest: late January, February, early March, plus late October–early November.
Most expensive: June–August (summer travel) and mid-December–early January.
Weather reality check: Chicago winters are brutally cold (well below 0°C, windy — hence the nickname), summers hot and humid. May–June and September are the comfortable middle — September often combines good weather with post-summer fares.
Events: summer festival season (June–August) fills hotels even when airfares soften slightly.

Money-saving tips for this route

Set alerts 4–5 months out and buy when the round trip drops below €450.
Consider flying into Midway with a connection — occasionally cheaper overall, though it adds a stop.
Check the fare families. On this route, “basic” transatlantic fares may exclude a full-size carry-on — the €60 saved can vanish at the gate.
Return-leg asymmetry: westbound flights are longer and pricier on average; if your dates are flexible, shift days on the outbound, not the return.
Open-jaw idea: fly into Chicago, out of New York (or vice versa) and cross the Midwest–East by domestic hop — sometimes the same total price with twice the trip.
