The route

Travel from the Pacific Northwest to the heart of the North Atlantic with Delta's direct seasonal service. Connecting Seattle-Tacoma International Airport to Keflavik International Airport, this route offers a streamlined path for travelers heading to Iceland's dramatic landscapes without the need for East Coast layovers.

This specific route, identified by the code DL-SEA-KEF, is a seasonal summer operation. Delta utilizes the Boeing 757-200 for this trans-Atlantic crossing, providing a consistent narrow-body experience for the approximately 7.5-hour journey.

As one of the few direct links between the US West Coast and Iceland, this route is essential for summer tourism. It bypasses major hubs like New York or Atlanta, saving several hours of travel time for those starting in the Pacific Northwest.
