United Airlines has announced the largest international expansion in its history with service to eight new cities, alongside the ramping up of services to many more.

Starting in May 2025, United will launch five new nonstop flights from its hub in Newark/New York to destinations no other U.S. airline serves including Nuuk, Greenland; Palermo, Italy; Bilbao, Spain; Madeira Island, Portugal and Faro, Portugal.

The airline is also adding three new nonstop routes from Washington D.C./Dulles, including its first-ever flight to Dakar, Senegal operating year-round and new seasonal nonstop flights to Nice, France and Venice, Italy.

United’s summer 2025 transatlantic schedule will be the largest in its history with more than 760 weekly flights.

In addition to new flights, customers will have even more time to explore Venice, Italy; Athens, Greece; and Barcelona, Spain with earlier start dates next summer.

The airline will also increase the number of weekly direct flights between Newark/New York-Palma de Mallorca, Spain, Newark/New York-Dubrovnik, Croatia, and Newark/New York-Athens, Greece.

United is also adding new direct flights from Tokyo-Narita to Ulaanbaatar, Mongolia and Kaohsiung – destinations no other U.S. airline serves – and a new nonstop flight to Koror, Palau.

These new flights will seamlessly connect in Tokyo to United’s transpacific services to five hub locations in the continental United States.

“No other airline gives customers nonstop access to as many unique international destinations and experiences from the U.S. as United,” said United’s Senior Vice President of Global Network Planning and Alliances, Patrick Quayle.

“Our network provides the most choice and variety for our customers, whether they are looking for a relaxing seaside getaway, once-in-a-lifetime adventure travel or to explore some of the most vibrant urban escapes across the globe.”

This expansion comes on the heels of the latest chapter of United’s award-winning ‘Good Leads The Way’ brand advertising campaign, which debuted earlier this month.

The latest iteration of the campaign highlights United’s position as the world’s largest airline and showcases how United’s network gives customers the most flexibility and options to travel across the globe.

In addition to the new destinations coming to United’s global network, the airline will also expand service to some its most popular international destinations.

United will add a year-round, nonstop flight between Tokyo/Narita-Koror, Palau. United is the only U.S. airline to serve Palau, with its existing service from Guam and Manila, and this new flight will enable easy one-stop connections for travelers coming from the U.S. to experience the pristine marine ecosystems.

Starting May 22, United will begin seasonal daily nonstop flying to Venice, Italy from Washington/Dulles, complementing its existing service from Newark/New York.

The airline will also begin seasonal, four-times weekly Washington/Dulles-Nice, France flights on May 24, in addition to its existing daily seasonal service from Newark/New York.

United will resume service to several destinations earlier in the season to give customers more time to explore next summer.

From Newark/New York, United will resume service to Athens, Greece on March 6; Venice, Italy on March 29 and Dubrovnik, Croatia, which will also increase to daily service, on May 1.

Additionally on May 1, United will resume service between San Francisco-Barcelona and Chicago O’Hare-Athens, which will be operated on a larger Boeing 787-10 aircraft.

The airline will also increase its flying between Newark/New York and Palma de Mallorca, Spain with four weekly flights.

On top of United’s historic expansion across the Atlantic and Pacific, United is also growing its network in Mexico and Central America.

Starting April 5, United will be the first and only airline to connect the United States to Puerto Escondido, Mexico with a nonstop once weekly, year-round flight from Houston operated by United Express partner Mesa Airlines on Embraer 175 aircraft.

With this new flight, United will serve 23 destinations in Mexico, and 65 destinations in the broader Latin and Caribbean region following the recent addition of Dominica service from Newark/New York launching on February 15, 2025.

Starting May 22, United also will add a new daily flight between San Francisco and San Jose, Costa Rica utilising Boeing 737-MAX8 aircraft.

United will now connect San Jose with all seven of its U.S. hubs, further building on its position as the largest U.S. carrier to Costa Rica and Central America.
