Sit on the Left side of the plane for the best views on flights from Washington to Madrid. While takeoff favors the right for Washington landmarks, the landing approach on the left side offers more dramatic and sustained views of the Sierra de Guadarrama and Madrid's geography. The left side also provides better views during the transatlantic cruise over the Atlantic and approaching European landfall.

During takeoff from Ronald Reagan Washington National (DCA), sit on the Right side for the best views. DCA typically departs runway 01 (northbound) or 19 (southbound). Right-side seats on northbound departures offer views of the Potomac River's northern reaches and Arlington, while southbound departures on the right show the Capitol and National Mall receding beneath you. Either direction favors the right for Washington's core landmarks. Notable sights include: U.S. Capitol building and National Mall, Potomac River (curving through central Washington), Arlington National Cemetery and Pentagon area, Washington Monument.

When landing at Barajas (MAD), sit on the Left side for the best views. Madrid typically lands on runways 32L/32R (from the northwest). Left-side seats on approach from the northwest provide excellent views of the Sierra de Guadarrama mountains and the Tagus River valley as you descend toward the airport. The city of Madrid itself spreads across the left side during final approach. Notable sights include: Sierra de Guadarrama mountain range (northwest of Madrid), Tagus River valley, Madrid city center with its urban sprawl, Barajas Airport runways and surrounding industrial areas.

The flight from Ronald Reagan Washington National (DCA) to Barajas (MAD) takes Approximately 7.5 to 8 hours.

The flight crosses the Atlantic Ocean for roughly 5 hours. Notable geographic features along the route include: the Appalachian Mountains visible shortly after departure (if climbing northeastward); the Atlantic coastline of Nova Scotia and Newfoundland receding to the north; the Mid-Atlantic Ridge (not visible but the flight path crosses above it); the western approaches to Ireland and the British Isles appearing as landfall after 6+ hours; the Irish Sea and Celtic Sea; Wales and southwestern England; the Bay of Biscay; and finally the Iberian Peninsula with Portugal's western coast and the Spanish interior plateau (Meseta Central) before descent into Madrid.
