Chicago O'Hare (ORD) lies about 27 km northwest of downtown and connects via the CTA Blue Line train in roughly 45 minutes, plus taxis and ride apps.

Allow a generous buffer for any onward domestic flight, and keep your documents ready for the inspection queue.

Greater Chicago hosts a sizeable Bengali and broader Indian community, with cultural associations, Durga Puja celebrations, temples and Indian restaurants in suburbs like Schaumburg and Naperville. Many fly for family visits, weddings, study and work in academia, healthcare and IT. Beyond community, Chicago offers Lake Michigan, world-class museums, the Willis Tower skydeck and onward connections across the US Midwest.
