Sit on the Right side of the plane for the best views on flights from Manchester to Washington. While takeoff from Manchester slightly favors the left side with White Mountains views, the landing approach into DCA on the right side is significantly more scenic, featuring the iconic Potomac River, Washington Monument, and National Mall—recognizable landmarks visible from altitude. The landing experience outweighs the modest takeoff advantage, making right the better overall choice for this route.

During takeoff from Manchester-Boston Regional Airport (MHT), sit on the Left side for the best views. Left side captures Manchester's departure over the White Mountains foothills and the Merrimack River valley, offering immediate terrain variation. Right side departs over relatively flat terrain toward the Atlantic. Notable sights include: White Mountains (distant northeast), Merrimack River valley, Lake Winnipesaukee (visible on clear days), New Hampshire's central highlands.

When landing at Ronald Reagan Washington National (DCA), sit on the Right side for the best views. Right side provides the superior landing approach into DCA, with views of the Potomac River, Washington Monument, and the National Mall during descent. Left side shows the Appalachian foothills receding behind. Notable sights include: Potomac River, Washington Monument, Lincoln Memorial, National Mall, Arlington National Cemetery.

The flight from Manchester-Boston Regional Airport (MHT) to Ronald Reagan Washington National (DCA) takes 1h 25m.

Appalachian Mountains (central Pennsylvania and Maryland ridges), Susquehanna River, Delaware River valley, Hudson River valley (if northerly routing), various reservoirs and lakes throughout Pennsylvania and New York
