United and Air Canada Are Launching New Nonstop Flights to Sapporo

United is scheduled to start SFO to CTS service on December 11, 2026. The airline says the route will operate three times a week during the winter season, from December through March, on a Boeing 787-9. It is listed as the first nonstop link between the continental United States and Sapporo, a narrower and still accurate claim now that Air Canada has announced its Vancouver route.

San Francisco is the key qualifier. Travelers in other parts of the United States generally will still need to connect to SFO, although United says its San Francisco network can feed the flight from nearly 80 U.S. cities. That can be attractive for a Hokkaido-first itinerary, but the usefulness depends on whether the connection and the three-weekly schedule line up with the trip.

The biggest benefit is itinerary flexibility, not a universal promise of a lower fare or a shorter total journey. For a trip built around Sapporo, Niseko, Rusutsu, Furano, Hokkaido skiing, or the Sapporo Snow Festival, arriving at CTS can eliminate a separate domestic flight after reaching Tokyo or Osaka. It can also make an itinerary that starts in Hokkaido feel more natural before continuing south through Japan.

For a broader visit, the established connection through Tokyo may still be better. A Tokyo stop, a central or western Japan leg, a materially better fare, or a mismatch with the seasonal operating days can all make a one-stop itinerary the smarter choice. Use the new services as additional choices, then compare the full trip rather than the nonstop label alone.

Both services are seasonal, and three flights a week leaves less room to recover from a schedule change than a daily route. Check the airline directly for the current operating day, aircraft, baggage terms, connection rules, and fare before committing to hotels or ski arrangements. Published schedules can change.

For a winter trip, also build the ground transfer into the plan. CTS serves the Sapporo region well, but it is not central Sapporo. Travelers headed to a resort should compare the onward train, coach, private transfer, and car options for their exact arrival time, especially if carrying ski equipment or arriving late in the day.
