Sit on the Right side of the plane for the best views on flights from Washington to Manchester. Both sides score equally for the full flight, but the right side edges ahead for landing approach scenery. The descent into Manchester offers better geographic variety with the Merrimack River valley and New Hampshire's terrain features. The takeoff from DCA is slightly more scenic on the left with DC's urban landmarks, but the landing advantage on the right provides the stronger overall experience for this route.

During takeoff from Ronald Reagan Washington National (DCA), sit on the Left side for the best views. Left side captures the Potomac River and Washington DC urban landscape during departure from DCA, with the National Mall, Capitol Building, and Arlington visible. Right side shows suburban Virginia and Maryland with less distinctive urban character. Notable sights include: Potomac River, Washington Monument area, Arlington National Cemetery, Theodore Roosevelt Island.

When landing at Manchester-Boston Regional Airport (MHT), sit on the Right side for the best views. Right side offers views of the Merrimack River valley and New Hampshire's rolling terrain as the aircraft descends toward Manchester. Left side shows less distinctive features—primarily forested areas and suburban sprawl without major geographic landmarks. Notable sights include: Merrimack River, Manchester city center, White Mountains (distant), New Hampshire lakes region.

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