Brussels (BRU) → Chicago (ORD): cheap fares overview
Brussels to Chicago is a transatlantic route where prices can swing wildly depending on the time of year. UA runs the only non-stop — about 7h 51m and just under 6,700 km — so when that fare climbs, you're either paying up or connecting somewhere. And connecting flights aren't always cheaper, by the way. Demand from business travelers keeps prices elevated through spring and autumn, while summer school holidays on both sides of the Atlantic push fares up hard from late June. January and February are typically your sweet spot — less competition, fewer people flying for fun.
Why travel from Brussels to Chicago?
Chicago pulls a surprisingly specific crowd from Belgium. There's a massive Polish-American community on the city's northwest side, and a lot of Belgians have family connections through broader European diaspora networks. But honestly? A lot of my Belgian friends go purely for the food — deep dish debates aside, the restaurant scene here genuinely competes with anything in Europe. Then there's architecture. Chicago's skyline isn't just pretty, it's a textbook — the city basically invented modern American architecture and there are tours that'll ruin you for other cities. Add in the blues scene, the art institute, and the fact that ORD connects onward to 282 destinations if you're doing a bigger USA trip — it's a seriously underrated first stop in America.
How to find a cheap fare on this route
Book at least 6-8 weeks out for summer, but for winter travel, last-minute can actually work in your favor. January and February consistently show the lowest fares on this route. If you're flexible, check whether connecting through Amsterdam, London, or Frankfurt undercuts the UA non-stop — sometimes by a lot. On the Brussels end, BRU serves 183 non-stop destinations so you've got options for positioning flights too. Use a price calendar view rather than searching fixed dates — shifting by even 2-3 days can change the fare significantly. Midweek departures — Tuesday or Wednesday — tend to be quieter and cheaper on transatlantic routes.
