The carrier confirmed the new services on 21 May. A year-round daily flight from Chicago O'Hare (ORD) to Tokyo Narita (NRT) launches on 24 October, operated on a Boeing 787-8. A seasonal service from San Francisco (SFO) to Sapporo's New Chitose Airport (CTS) will run three times a week from December through March on a Boeing 787-9 Dreamliner.
Chicago to Tokyo Narita - the Nagano gateway
Tokyo Narita is the more useful airport for skiers heading to the mountains of Nagano Prefecture. It sits on the eastern side of greater Tokyo and connects directly into Japan's Shinkansen network, making resorts like Hakuba Valley accessible without an overnight in the city.
The new Chicago-Narita route complements United's existing Chicago to Tokyo Haneda (HND) service. Haneda is the more convenient option for travellers staying in central Tokyo; Narita is the better choice for anyone heading straight to the snow.
