What Does Business Class from Chicago to Sydney Cost?
Business class from Chicago to Sydney is one of the longest and most premium-demand transpacific routes in North America, and CEOFLIGHTS clients regularly secure round-trip fares between $3,800 and $9,300 — compared to published retail rates that frequently exceed that upper range. The route connects O'Hare International Airport (ORD) to Sydney Kingsford Smith Airport (SYD), spanning roughly 15 hours of flight time across the North America to Oceania corridor.
Three major carriers operate this route with business class service: United Airlines, Qantas, and Delta Air Lines. Each offers a meaningfully different onboard experience, routing structure, and fare availability at any given time. United typically operates via its hub connections, Qantas leverages its home-market strength on transpacific flying, and Delta connects through its Pacific network — giving travelers genuine options rather than a single default choice.
