United is adding 10 international cities and three additional routes in 2027, marking what the carrier describes as the largest international network expansion in its 100-year history.
The new destinations include Okinawa, Japan, from San Francisco; Toulouse, France, from Washington Dulles; and eight cities from Newark: Luxembourg City; Marseille, France; Ibiza and Valencia, Spain; Terceira, Portugal; Ljubljana, Slovenia; and the Italian cities of Olbia and Catania.
Eight of the destinations are not served by another U.S. airline, while seven currently have no nonstop service to the U.S., according to United.
Three weekly flights between San Francisco and Okinawa will begin March 27 and operate with a Boeing 777-200 through Oct. 27.
Daily, year-round Newark-Luxembourg service will begin April 2, followed by daily, year-round Washington Dulles-Toulouse flights on April 26. Both routes will use United’s new Airbus A321XLR.
During a news conference on Monday, Patrick Quayle, United’s senior vice president of global network planning and alliances, said the Toulouse route is partly designed to connect Airbus’ North American headquarters near Dulles with the manufacturer’s global headquarters in France.
United will add four weekly Newark-Ljubljana flights on May 12, three weekly flights to Olbia on May 27, and four weekly flights to Catania on May 28. The routes will operate through late September or October using Boeing 767 aircraft.
Four-times-weekly service from Newark to Ibiza will begin May 31, followed by three weekly Valencia flights on June 2 and daily service to Marseille on June 4. All three will use the A321XLR and operate into October.
The final new destination, Terceira in Portugal’s Azores, will receive three weekly Boeing 737 MAX 8 flights from Newark between June 9 and Sept. 5.

More New Routes
Beyond the 10 new cities, United will add daily, year-round service from Los Angeles to Osaka, Japan, beginning March 27. The route will use a Boeing 787-9 and complement existing Osaka flights from San Francisco and Guam.
Quayle said favorable exchange rates are contributing to U.S.-originating demand for Japan, along with broader interest in the country.
“The yen does play a factor into that and the fact that it’s very affordable, very much so versus the past,” he said.
United will also add daily, year-round Denver-Paris service on May 27 and three weekly flights between Washington Dulles and Milan beginning May 28. Quayle described Milan as the largest unserved international market from Dulles.
The airline is separately planning to restart year-round service between San Francisco and Tel Aviv on March 28. Flights will operate three times weekly with a Boeing 787-9.
United said the expansion will not come at the expense of existing international routes.
“Everything is coming back,” Quayle said. “We’re not dropping any routes in order to fund this.”
Eight of the 10 new destinations will operate from Newark. Asked whether the airport could accommodate the additional flying, Quayle pointed to the FAA’s enforcement of flight caps and Newark’s recent operating performance.
“Newark has been the most reliable of the big three New York airports,” he said. “The FAA has been enforcing the caps, and it’s operating incredibly well.”
United will also bring back four destinations introduced from Newark during summer 2026: Split, Croatia; Bari, Italy; Glasgow, Scotland; and Santiago de Compostela, Spain.
The carrier said it will serve 53 destinations across the Atlantic and 34 across the Pacific in 2027.
