The route

This route connects the capital of the United States with the volcanic landscapes of Iceland. Starting in 2026, United offers year-round daily service, making it easier than ever for travelers to access the Northern Lights and geothermal spas from the Mid-Atlantic region.

This route signifies United's expansion into year-round North Atlantic service. It serves as a primary gateway for East Coast travelers avoiding the busier New York hubs while offering a premium narrow-body experience.
