Cheap flights from Busan to Chicago

The weeks on either side of October often avoid the heaviest holiday demand, and October is the cheapest month for this route. Midweek departures can be easier than weekend ones, while school holidays, summer travel and the Christmas period usually push fares and crowds up. If your dates are flexible, compare the days around your preferred week rather than a single fixed date.

Every option on this route connects, so each itinerary adds a transfer, a second departure and arrival, and sometimes a change of terminal. Korean Air, Eva Air, Philippine Airlines, China Airlines, Vietnam Airlines, Air China and China Eastern are generally full-service carriers whose fares more often include checked baggage and meals; Jeju Air and Hong Kong Express Airways are low-cost and usually charge for bags and seats; Starlux sits closer to the full-service end. What matters in practice is ticket protection: one booking with a connection is usually rebooked if the first flight is late, while two tickets bought separately leave a missed connection to you.

Getting into Chicago from either airport is straightforward but not identical. O'Hare International has fast rail links and a big-terminal layout that can mean long walks, while Midway International is smaller and its rapid transit line runs directly towards the city centre. Taxis and ride-hailing are useful late at night or with heavy bags, but road traffic can make them slow, so check whether your train is still running before you rely on it. Whichever airport your ticket names, allow extra time on arrival if you are connecting to a hotel, another flight or a train.
