There is no nonstop flight from Chicago to Tanzania. From O'Hare you'll fly one connection — Qatar Airways via Doha or Turkish Airlines via Istanbul — onto the direct hub–JRO services, for a total journey of 20+ hours. Published 2026 round-trip fares from Chicago run $1,000–$1,500(Tanzania-Safaris, 2026), second only to New York's band. Book one ticket, keep the connection comfortable, land at JRO (not Dar) for a northern-circuit safari, and carry your first 48 hours on board. The complete US routing picture: flights from the USA guide.

Chicago's two clean one-stops:

• Qatar Airways via Doha (from ORD) — onto the direct Doha–JRO service (four weekly); usually the structure to price first.
• Turkish Airlines via Istanbul (from ORD) — the competing one-stop; whichever prices better on your dates wins.

Amsterdam-path routings also work from Chicago via partner connections into KLM's daily Amsterdam–JRO service — fine when the through-fare is right, just keep it on one ticket so the airline owns any missed connection, not you. Midwest winters add one practical note for December–February departures: build slack at the O'Hare end and favour comfortable connections — the winter-departure buffer advice applies squarely to Chicago. Arrival airport is settled as ever: JRO, an hour from Arusha.

Published 2026 round trips from Chicago run $1,000–$1,500(Tanzania-Safaris, 2026). The standard playbook applies: 5–6 months ahead for July–August and Christmas, a 2–8-month window otherwise, and no separate-ticket self-transfers to shave $100 — the risk maths never favours it on a trip this size. Where the flight sits in the total budget: Tanzania safari from the USA.
