United Airlines has just announced its major international expansion for 2026. The airline has been teasing that we can expect new routes, and the details are now out. United has by far the most interesting route network of any US carrier (United flies to the most destinations and most countries of any US carrier), so I always look forward to seeing what creative new routes the airline comes up with.
Admittedly United is fairly limited in terms of its potential growth, given that the airline isn’t taking delivery of many new long haul aircraft. So I’d say these additions are exciting, but perhaps not quite as splashy as last year’s new routes to Greenland, Mongolia, and beyond.
United Airlines launching several new international routes
In 2026, United Airlines is adding service to four new international destinations, and is adding two new long haul routes to existing international destinations. So it’s a bit less exciting than last summer, when United added service to eight new international destinations, but I also wasn’t expecting that level of growth (for what it’s worth, all of last year’s new destinations are being brought back, which is impressive).
Here’s how Patrick Quayle, United’s SVP of Global Network Planning and Alliances, describes this:
“United has an unmatched international network, and we pride ourselves on connecting our customers to unique, trendsetting destinations no other U.S. airline serves. With the addition of these new flights and the return of all of our new routes from last year, United now flies to 46 cities across the Atlantic – more than any other airline – and is the clear flag carrier of the U.S.”
So let’s start with the four routes being added to all-new destinations, and then we’ll look at two new routes to existing destinations.
United’s Newark (EWR) to Bari, Italy (BRI) route
As of May 1, 2026, United will launch 4x weekly summer seasonal service to Bari, Italy, United will be the only US airline flying to Bari. United plans to use a Boeing 767-300ER for the 4,515-mile route.
United’s Newark (EWR) to Glasgow, Scotland (GLA) route
As of May 8, 2026, United will launch daily summer seasonal service to Glasgow, Scotland. United will be the only US airline flying to Glasgow, Scotland’s biggest city. United plans to use a Boeing 737 MAX 8 for the 3,228-mile route.
United’s Newark (EWR) to Santiago de Compostela, Spain (SCQ) route
As of May 22, 2026, United will launch 3x weekly summer seasonal service to Santiago de Compostela, Spain. United will be the only US airline flying to Santiago de Compostela. United plans to use a Boeing 737 MAX 8 for the 3,310-mile route.
United’s Newark (EWR) to Split, Croatia (SPU) route
As of April 30, 2026, United will launch 3x weekly summer seasonal service to Split, Croatia. United will be the only US airline flying to Split. United plans to use a Boeing 767-300ER for the 4,406-mile route.
United’s Washington (IAD) to Reykjavik, Iceland (KEF) route
As of May 21, 2026, United will launch daily summer seasonal service between Washington Dulles and Reykjavik, complementing existing service out of Chicago and Newark. United plans to use a Boeing 757-200 for the 2,799-mile route.
United’s Newark (EWR) to Seoul, South Korea (ICN) route
As of September 4, 2026, United will launch daily year round service between Newark and Seoul Incheon, complementing existing service out of San Francisco. United plans to use a Boeing 787-9 for the route.
Bottom line
United Airlines has announced plans to launch six new international routes in 2026. This includes service to four new European destinations, plus additional routes to two existing international destinations. Of note is that United will be the only US carrier to service these four new destinations. Then again, two of the routes are being served by Boeing 737s, so in terms of passenger experience, that leaves a bit to be desired.
What do you make of United’s latest international expansion?
