United's biggest-ever international expansion includes 10 destinations worth a closer look

Ever wanted to fly nonstop to Slovenia? You're in Luxembourg!

United Airlines on Tuesday announced what the airline says is the largest expansion in its history, with 10 new international destinations — including the first nonstop flights by a U.S. airline to Ljubljana, Slovenia and Luxembourg City — and 13 new routes.

"We've opened up more of the world to our customers," Patrick Quayle, United's senior vice president of global network planning, said on a conference call with reporters . "Next summer, we'll give them more opportunities … to explore places that they may not have previously considered."

Beginning in March 2027 and continuing into the summer, United will launch nonstop service to the following destinations across Europe and Asia:

Luxembourg City, Luxembourg — from Newark

Terceira, Azores, Portugal — from Newark

Toulouse, France — from Washington Dulles

The flights to Ibiza, Valencia, Luxembourg City, Marseille and Toulouse will be aboard United's new Airbus A321XLR. The plane is scheduled to begin flying select domestic routes in September, followed by international service in December.

The Chicago-based carrier has added nearly 60 international destinations to its route map since 2017, and now flies to more than 160 international destinations.

United is also adding new international routes to destinations it already serves from three of its U.S. hubs: daily service from Los Angeles to Osaka, Japan; nonstop service from Washington, D.C., to Milan, Italy; and daily nonstop service from Denver to Paris.

The airline said it will also resume three-times-weekly service from San Francisco to Tel Aviv on March 28, 2027.
