United Launches New Dulles-Costa Rica Nonstop For Holiday Travelers

DULLES, VA — United Airlines is expanding its international network from Washington Dulles International Airport with a new seasonal nonstop route to Liberia, Costa Rica, timed for the winter holiday travel season.

The daily seasonal service will begin Dec. 17 and operate through Jan. 4 aboard a Boeing 737. According to United, it will be the only nonstop flight between Washington Dulles and Liberia.

The new route gives travelers in the Washington region another nonstop option for visiting Costa Rica during one of the busiest travel periods of the year. Liberia serves as a gateway to many of the country's Pacific coast beaches and national parks.

United Expands Costa Rica Service

The Liberia route joins United's existing seasonal nonstop service from Dulles to San José, giving travelers two nonstop destinations in Costa Rica.

"This new Liberia flight gives D.C.-area travelers a nonstop way to trade our region's winter weather for Costa Rica's beaches and national parks," Henry Bird, managing director of United's Dulles hub, said in a statement. "As the DMV's largest and most on-time major airline, United continues to grow our Dulles hub with more nonstop destinations and an elevated travel experience."

According to the airline, United now offers nonstop service from Dulles to 19 destinations in Latin America, more than any other airline serving the Washington metropolitan area.

Sixth New International Route This Year

The Liberia flight marks United's sixth new international destination announced from Washington Dulles this year as the airline continues expanding its hub.

Other international routes launching in 2026 include Reykjavík, Iceland; Halifax, Nova Scotia; Québec City, Quebec; Los Cabos, Mexico, beginning Oct. 25; and Cartagena, Colombia, which also launches Dec. 17.

United said the Liberia service is scheduled to operate daily during the peak holiday travel period before concluding on Jan. 4.
