Sit on the Right for takeoff, Left for landing side of the plane for the best views on flights from Washington to Keflavik. This transatlantic route offers distinct scenic advantages on each side. Takeoff from DCA favors the right for Washington's monuments and the Potomac River. Landing into Keflavik strongly favors the left for Iceland's volcanic coastline and lava fields—the most visually distinctive feature of the entire flight. If forced to choose one seat for the full journey, left wins because the Icelandic approach is more dramatic and memorable than the Washington departure.

During takeoff from Ronald Reagan Washington National (DCA), sit on the Right side for the best views. Right-side seats offer views of the Potomac River and Washington, D.C.'s monumental core during the northeastward climb-out from DCA. The Capitol, Lincoln Memorial, and the river's distinctive curves are visible for several minutes as the aircraft gains altitude over northern Virginia. Notable sights include: Potomac River, U.S. Capitol Building, Lincoln Memorial, Arlington National Cemetery.

When landing at Keflavik Nas (KEF), sit on the Left side for the best views. Left-side seats provide views of Iceland's dramatic southwestern coastline and the Reykjanes Peninsula during descent into Keflavik. The black lava fields, coastal cliffs, and the Atlantic Ocean are striking features visible 20-30 minutes before touchdown. Notable sights include: Reykjanes Peninsula lava fields, Atlantic coastline, Keflavik Bay, Icelandic glacial valleys inland.

The flight from Ronald Reagan Washington National (DCA) to Keflavik Nas (KEF) takes Approximately 7 hours 15 minutes.

The flight path crosses the Atlantic northeast from Washington, passing over the Mid-Atlantic states, New England, and the Canadian Maritimes before heading over open ocean. Notable features include the Appalachian Mountains visible during the first 90 minutes of flight (best from the right side), the New England coastline and Cape Cod area, and then 5+ hours of open Atlantic Ocean with occasional views of the Greenland ice sheet's southern edge on the left side during the final 2-3 hours before approaching Iceland. The transition from North American landmass to open ocean to Icelandic volcanic terrain represents the full geographic arc of the journey.
