Connecting through Chicago O’Hare saves 20—40% on fares to Midwest and secondary East Coast cities compared to direct flights. Shanghai to New York via Chicago runs $620—$895, versus $825—$1,240 direct. With 200+ domestic connections and same-terminal bag through-check on United, O’Hare is the most efficient US hub for Chinese travelers.
Allow minimum 3 hours for your O’Hare connection. ORD is notorious for delays. If your layover stretches to 5—8 hours, exit the airport (US visa required) and visit Millennium Park or the Art Institute — both are 45 minutes downtown by metro.

Chicago Transit Guide

With 5-8 hours: Exit airport to visit Millennium Park, Art Institute, or Navy Pier. Metro takes ~45 minutes downtown. US visa required to exit the airport.
Baggage Policy
Same-airline or same-alliance connecting tickets: bags check through to final destination. Separately purchased tickets: must claim and re-check bags at O’Hare.
Bottom line: Chicago O’Hare offers a 20—40% price advantage over direct flights to the same US city, the highest domestic connection density, and smooth same-alliance transfers. Choose it when flying to Midwest or East Coast secondary cities, or when direct fares are prohibitive.
FAQ
Q: Is O’Hare better than LAX or SFO for connections? A: For Midwest and East Coast destinations, yes. O’Hare has far more domestic connections than LAX or SFO. For West Coast destinations (Portland, Phoenix, Vegas), LAX or SFO connections are faster and often cheaper.
Q: Can I leave the airport during a long layover? A: Yes, if you have a valid US visa and are on a connecting ticket (not two separate bookings). Allow at least 3 hours to clear security on return. The CTA Blue Line takes 45 minutes to downtown Chicago.
Q: What happens if I miss my connection due to a delay? A: On the same booking (same airline or codeshare), the airline is obligated to rebook you at no charge. On separately purchased tickets, you are on your own — this is why same-alliance connecting tickets are worth the slightly higher fare.
