Just a tidbit..
The US's New Entries In The Longest Continental US Flights List
Let's focus on Q3 2026 (June-September), when United's flights between Los Angeles/San Francisco and Portland will be operating. Doing so shows that both routes will be within the country's ten longest flights within the Lower 48 states list.
In fact, it is a bit more than that. On a great circle basis, San Francisco-Portland will be within a whisker of being number one. Just one nautical mile (!) separates it from what remains in pole position, Seattle to Miami. That city pair has been first for a long time.
United's Two New Transcon Routes To Portland
Two of the most intriguing additions involve the most populous city and metro area in Maine. On June 20, United will take off from Los Angeles to Portland, with a Saturday-only, Boeing 737-800-operated service. On June 27, the carrier will inaugurate flights from San Francisco to Portland, with the same operation and equipment. Both never-before-served routes will operate until September 19.
US Department of Transportation data for the 12 months to June 2025 shows that Los Angeles-Portland had 31,900 round-trip passengers (44 passengers daily each way), while San Francisco had 27,700 (PDEW: 38). Both were pretty good-sized markets. Obviously, the summer was critical, with Q3 (July-September) accounting for 36% to 39% of each route's traffic. Hence, United's time-limited, peak-season operation.
Of course, passengers can already easily fly between Los Angeles/San Francisco and Portland via multiple hubs. There are many one-stop options to choose from. Still, the brand-new nonstop offerings are low-risk endeavors, with only 166 seats to fill each way, each week. And even more intriguingly, they are overwhelmingly Portland's new two longest-ever routes. They surpass the distance of what was number one, Denver, by up to 53%.
