United Airlines, the world's largest airline by destinations served, has quietly removed six airports from its network in 2026 — and several won't be coming back. Only one of the cuts is international: Dakar, Senegal, which United served from Washington Dulles with a 767-300ER three times a week. The route lasted less than a year, launched on the back of United's paid-off, flexible 767 fleet. Despite competing alongside Delta's New York JFK service, the flights struggled — largely because the timing didn't connect well with Dulles traffic and the airline ran it year-round rather than seasonally.
The other five cuts are all small US markets: Nantucket, Massachusetts; Pellston, Michigan; Rhinelander, Wisconsin; and West Yellowstone, Montana, all ending by October 2026. Notably, none are scheduled to return. Nantucket and Yellowstone would normally resume each summer, but United's schedule now runs through next September with nothing bookable — a strong sign these routes are gone for good.
The Yellowstone story is the most instructive. United debuted at Yellowstone Airport (WYS) in June 2021, a pandemic-era bet on outdoor holidays, flying up to three times daily from Denver. Once travel normalised, volumes collapsed from 238 departures in 2021 to around 35 a year by 2024. Even a rebound to 219 departures in 2026 couldn't fix the economics: load factors rarely topped 58% before 2025, and the route ranked just 152nd out of 169 Denver routes for revenue per seat mile. Meanwhile, nearby Yellowstone Regional Airport in Cody, Wyoming — a different airport entirely — consistently filled 74-84% of its seats and remains on sale for next year. Practical takeaway: travellers heading to the park's west entrance should expect to route through Bozeman or Jackson Hole instead.
There's a broader pattern here. Route churn is constant across the industry — WestJet recently dropped 13 international destinations and Air Canada six, partly driven by the end of Cuba services. Even United, which will touch 395 airports between now and next summer, trims constantly. The flip side for travellers: United is still expanding into new and unusual places, including Nuuk in Greenland and Adelaide in Australia — both seasonal, both with United as the only North American carrier flying there. If those appeal, book early and don't assume they'll last forever.
For holiday planners, the message is simple: small, experimental routes — whether a West African capital or a gateway to a national park — can vanish with little notice. If a niche United route is central to your trip, keep an eye on alternatives before you lock in hotels.
