This page does one job: keep an eye on return fares from Stuttgart to Chicago. You get the cheapest price we have on record, the exact dates it was available on, and how that sits against what the route normally costs.
Prices are re-checked against Skyscanner automatically, and every one shows when it was last confirmed, so nothing here is older than it looks. Not flying from Stuttgart? We track 59 other departure cities for Chicago, listed at the foot of this page.
Prices like this tend to vanish fast. If it has gone when you look, try the days either side of the dates above, since Stuttgart to Chicago is often still worth booking within a day or two of the fare we found.
