Sit on the Right side of the plane for the best views on flights from Washington to Miami. While the left side has the better takeoff view over Washington DC, the right side wins overall because the Miami approach over Biscayne Bay and the Atlantic coastline is one of the most spectacular arrival views in domestic US aviation. The right side also tracks the Atlantic coastline through the Carolinas and Georgia, keeping the ocean in view for much of the cruise phase.

During takeoff from Washington Dulles International (IAD), sit on the Left side for the best views. Dulles typically departs east on runways 01L/01R or southeast on 19L/19R. On an eastbound departure, the left side gives a clear view back toward Washington DC — the Capitol dome, the Mall, and the Potomac River are all visible as the aircraft banks south. The right side faces suburban Virginia with little of note. Notable sights include: Washington DC Mall and Capitol, Potomac River, Reagan National Airport below, Chesapeake Bay in the distance.

When landing at Miami International (MIA), sit on the Right side for the best views. Miami International typically receives arrivals from the north on runways 08R/08L or 12, with approaches often coming in over the western suburbs. The right side on approach gives views over Biscayne Bay, Miami Beach barrier island, the downtown Miami skyline, and the turquoise shallow waters of the bay — among the most visually striking approach views in the US. The left side faces inland toward the Everglades. Notable sights include: Biscayne Bay, Miami Beach barrier island, Downtown Miami skyline, Port of Miami cruise terminals.

The flight from Washington Dulles International (IAD) to Miami International (MIA) takes Approximately 2 hours 45 minutes to 3 hours.

The flight tracks roughly south-southeast along the Atlantic Seaboard. Notable features include the Outer Banks of North Carolina (a thin barrier island chain visible from altitude), the broad mouth of the Cape Fear River near Wilmington NC, the South Carolina and Georgia coastlines with their sea island chains and tidal marshes, the Jacksonville FL metro area, the Space Coast near Cape Canaveral with its distinctive launch complex structures, and Lake Okeechobee — a large circular inland lake visible in central Florida before the descent into Miami.
