United Airlines announced Thursday that it is launching flights to eight new destinations abroad, in what the airline describes as its largest international expansion ever.

Starting next May, United will fly nonstop to new cities on several continents, including seven locations that the airline says are not served by any other U.S. carrier. In total, customers can book tickets for flights on 11 new routes.

These are the new cities the airline will fly to in 2025:

• Bilbao, Spain
• Dakar, Senegal
• Faro, Portugal
• Kaohsiung, Taiwan
• Madeira Island, Portugal
• Nuuk, Greenland
• Palermo, Italy
• Ulaanbaatar, Mongolia

United first began flying to Africa in 2019 and with the addition of Dakar, Senegal, will serve six cities on the continent.

The airline is also adding new nonstop routes to cities it already serves, United said. For example, it is adding flights between Washington Dulles International Airport and Nice, France. In addition, it will add a nonstop flight between Tokyo and Narita-Koror, Palau, as well as flights from Houston, Texas, to Puerto Escondido, Mexico, and between San Francisco and San Jose, Costa Rica.
