New Direct Flight from Washington to Guanacaste Opens Costa Rica’s Pacific Coast

United Airlines will launch a daily direct flight from Washington Dulles to Liberia, Guanacaste, from December 17, 2026 to January 4, 2027, making it easier than ever to reach the rainforest and beaches of northern Costa Rica.

Actionable suggestion: Book a night at a lodge near Arenal Volcano for December 18 or 19, 2026, and plan a sunset hike to see the volcano’s glow after your direct flight lands.
