Route Briefing: Chicago to Seoul
Seoul has a way of making you feel like you've landed in the future and the past simultaneously, and the fact that you can get there nonstop from Chicago in around 14 and a half hours makes this one of the most rewarding long-haul routes you can book out of O'Hare. Korean Air and Asiana Airlines both fly this route and are consistently regarded as among the finest carriers in the world — the service, food, and cabin comfort on these flights genuinely take the edge off a transpacific journey.
Landing at Incheon International Airport is itself a pleasant experience. The airport is regularly ranked among the best in the world for cleanliness, efficiency, and amenities. From there, the AREX express train connects directly to central Seoul, dropping you at Seoul Station in roughly 45 minutes — it's affordable, reliable, and far less stressful than navigating traffic in a taxi after a long flight.
Seoul rewards curiosity at every turn. Spend a morning wandering the grounds of Gyeongbokgung Palace, where you can watch the changing of the guard ceremony in traditional dress, then lose an afternoon in the winding alleyways of Insadong browsing antique shops and tea houses. Contrast that with an evening in Gangnam or Hongdae, where the city's neon-lit, K-pop-soaked energy is impossible to resist. The street food scene alone justifies the flight — tteokbokki, Korean fried chicken, and hotteok are the kinds of things you'll be craving for months after you return.
Timing matters on this route. Summer, from June through August, and the stretch around Lunar New Year in late January or early February are peak periods, which means higher fares and bigger crowds. If your schedule is flexible, spring and autumn offer genuinely beautiful weather and a much more relaxed atmosphere. Whenever you go, booking three to six months out gives you the best shot at fares under $700 roundtrip — a remarkable value for a nonstop flight of this distance. Standard pricing runs between $1,000 and $1,400 or more, so planning ahead pays off in a real way.
One tip that seasoned Seoul travelers swear by: pick up a T-money card at the airport or any convenience store. It works on the metro, buses, and even some taxis, and the Seoul subway system is so extensive and easy to navigate that you may barely need anything else to get around the entire city.
