Sit on the Left side of the plane for the best views on flights from Keflavik to Washington. Left side wins both ends of the flight. At departure you get Iceland's most dramatic geography — Snæfellsjökull, Faxaflói Bay, and Reykjavik. At arrival you get Washington D.C. and the Potomac. Over the open North Atlantic the views are symmetric, but the bookends strongly favor the left.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Keflavik typically departs eastward on runway 28/10, meaning a left-side seat faces north toward the Snæfellsnes Peninsula and the Snæfellsjökull glacier-capped volcano. As the aircraft climbs and turns southeast toward the transatlantic track, the left side also captures Reykjavik city and Faxaflói Bay spread out below. Notable sights include: Snæfellsjökull glacier volcano to the north, Faxaflói Bay, Reykjavik city and harbor, Mount Esja ridge above the capital.

When landing at Washington Dulles International (IAD), sit on the Left side for the best views. Dulles typically receives arrivals from the northeast on runway 19L/19R heading south, or from the west on runway 01. On the standard approach from the northeast over the mid-Atlantic states, the left side faces east toward Washington D.C. itself — the National Mall, Potomac River, and the broader metro area are clearly visible during descent. The right side looks west into suburban Virginia with less to see. Notable sights include: Washington D.C. city center and National Mall, Potomac River, Chesapeake Bay visible earlier in descent, Blue Ridge Mountains to the west on right side.

The flight from Keflavik Nas (KEF) to Washington Dulles International (IAD) takes Approximately 6 to 7 hours.

The flight tracks southwest over the North Atlantic on standard NAT (North Atlantic Track) routing. Greenland's southern tip and iceberg-filled waters of the Labrador Sea may be visible early in the flight on the left side if routing passes near Cape Farewell. The flight then crosses the largely featureless open North Atlantic, with occasional iceberg fields visible at lower latitudes. Approaching North America, the coast of Newfoundland or Nova Scotia appears depending on the day's track, followed by the Gulf of Maine and New England coastline during descent.
