About This Route
Which side of the plane should I sit on flying from Heathrow (LHR) to Washington Dulles International (IAD)?
Sit on the Left side of the plane for the best views on flights from London to Washington. The right side wins at takeoff with the London view, but the left side delivers the superior landing approach over the Potomac and DC monuments — one of the most iconic urban approaches in aviation. Over the Atlantic the views are symmetric, so the left seat edges it overall for the destination payoff.
What can I see during takeoff from Heathrow in London?
During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow's dominant departure runways 27L/27R head westbound, so the right (north) side gives you a clear view back over central London as you climb out — the Thames snaking east toward the City, with the Wembley arch visible on clear days. The left side faces south toward Surrey suburbs with little of note. Notable sights include: Thames River bending east toward central London, Wembley Stadium arch, Windsor Castle and Windsor Great Park to the west, Staines Reservoirs directly below during climb-out.
What can I see when landing at Washington Dulles International in Washington?
When landing at Washington Dulles International (IAD), sit on the Left side for the best views. Dulles primarily uses runways 01L/01R or 19L/19R depending on winds. On the common southbound approach to runway 19, the left (east) side looks toward the Potomac River, the Washington Monument, Capitol Hill, and the broader DC skyline — genuinely one of the best urban approach views in the US. The right side faces west into the Virginia suburbs and Blue Ridge foothills. Notable sights include: Washington Monument and National Mall, Potomac River, Capitol Building dome, Arlington and the Pentagon visible just before touchdown.
How long is the flight from London to Washington?

Mid-ocean you may see sea ice or icebergs near the Labrador Sea. The Canadian coast is crossed near Newfoundland — St. John's and the rugged Avalon Peninsula are sometimes visible — before tracking southwest over Nova Scotia, New England, and the mid-Atlantic states into Virginia.
