United Airlines already serves (by far) the most destinations in Asia of any airline in the United States. The carrier has now revealed yet another new route to Asia, which is exciting.
United adds seasonal San Francisco to Sapporo route
In the winter 2026-2027 season, United will launch a new 3x weekly flight between San Francisco (SFO) and Sapporo (CTS). This new route to Japan route will run from December 17, 2026, through March 26, 2027, with the following schedule:
UA234 San Francisco to Sapporo departing 10:30AM arriving 2:15PM (+1 day)
UA235 Sapporo to San Francisco departing 4:15PM arriving 8:25AM
The service will operate westbound on Sundays, Wednesdays, and Fridays, and eastbound on Mondays, Thursdays, and Saturdays. The 4,796-mile flight is blocked at 10hr45min westbound and 9hr5min eastbound. Fun fact — this will be United’s shortest “true” transpacific route (from the continental United States) with regularly scheduled passenger service.
United will use a Boeing 787-9 for the flight, featuring 251 seats. This includes 48 business class seats, 21 premium economy seats, and 188 economy seats.
My take on United’s new flight to Sapporo, Japan
It’s cool to see United add yet another new destination in Asia, as the airline really is in a league of its own among US carriers when it comes to how creative its route network is.
As some may remember, last winter we went on a ski trip to Niseko (which is located in Hokkaido), as the region has some fantastic skiing. While Hokkaido has long been popular with skiers from all over Asia and Australia, it seems to also be increasingly popular with visitors from elsewhere, including North America, Europe, etc.
It’s fantastic to see United making it easier for those from North America to get to Sapporo. Given what a big connecting hub San Francisco is, this should enable all kinds of one-stop service from across North America.
This is such a brilliant use of an aircraft. US carriers focus heavily on Europe in the northern summer, given the insatiable demand for transatlantic travel. The challenge is always figuring out where to fly planes in winter.
Sure, there’s demand for South America and the South Pacific, and there’s also some demand for Southeast Asia. But I can’t think of any other long haul service that operates exclusively in winter that’s focused on skiing, quite like this route.
Now, the one thing that has to be acknowledged is that United is duplicating Air Canada’s new service here. The airline is also launching seasonal flights to Sapporo this upcoming winter, out of Vancouver (YVR). The airline is also operating 3x weekly flights, also with Boeing 787s, and the seasons are nearly identical (though I guess United wanted to beat Air Canada to the punch with the first nonstop flight from North America to Sapporo, as the service launches several days earlier).
Now, some of the brightest minds in route planning are United’s Patrick Quayle and Air Canada’s Mark Galardo, and they’re at the two North American carriers with the most interesting route networks. I imagine they were working off similar data in deciding on these routes.
I thought Sapporo service was a slam dunk when Air Canada announced it, and it’ll be interesting to see if the market can sustain two new direct links from North America. Air Canada and United are operating to Sapporo on different days of the week, and I imagine that’s intentional. Keep in mind that while the airlines have a joint venture across the Atlantic, that doesn’t apply across the Pacific, so there was no coordination here.
Bottom line
United Airlines will be launching a new 3x weekly winter seasonal flight between San Francisco and Sapporo as of December 2026. This is the second nonstop route between North America and Sapporo that has been announced in recent times, as Air Canada will also fly to Sapporo out of Vancouver.
This is an awesome new service, and I’m delighted to see United continuing to lead the way among US carriers when it comes to its global route network.
What do you make of United’s new Sapporo service?
