Sit on the Left side of the plane for the best views on flights from Palm Springs to Washington. Left side wins both ends of the flight — the dramatic San Jacinto escarpment at departure and the Potomac River and D.C. skyline on approach. During the cruise over the Southwest and mid-continent, the left side also tracks slightly more interesting terrain including the Colorado River corridor and Appalachian ridgelines on descent.

During takeoff from Palm Springs International (PSP), sit on the Left side for the best views. PSP's primary departure runway 31L sends aircraft northwest, then routes typically turn east. The left (south) side gets the dramatic San Jacinto Mountains rising abruptly from the valley floor — one of the steepest escarpments in North America at over 10,000 feet of relief. The Coachella Valley floor and Salton Sea are also visible to the southeast. Notable sights include: San Jacinto Peak and its sheer western escarpment, Salton Sea glinting to the southeast, Coachella Valley agricultural patchwork, Palm Springs urban grid against the desert floor.

When landing at Washington Dulles International (IAD), sit on the Left side for the best views. Dulles typically uses runways 01L/R or 19L/R depending on winds. On a westerly approach to runway 01, the left side faces east toward Washington D.C. proper — you get a clear view of the Potomac River, the National Mall corridor, and the Capitol dome on the horizon. On runway 19 approaches from the north, the left side still tracks the Potomac and the Virginia suburbs. Notable sights include: Potomac River winding toward D.C., National Mall and Capitol building on the horizon, Tysons Corner urban cluster in the Virginia suburbs, Blue Ridge Mountains visible to the west on clear days.

The flight from Palm Springs International (PSP) to Washington Dulles International (IAD) takes Approximately 4 hours 30 minutes to 5 hours.

The route crosses the Colorado River near the Arizona-Nevada border, then tracks over the Four Corners plateau region with the Colorado Plateau's canyon country visible on clear days. Over New Mexico and Texas the terrain flattens into the High Plains. The Mississippi River crossing occurs roughly over Missouri or Arkansas. The Appalachian Mountains — specifically the Ridge and Valley province of Virginia and West Virginia — are crossed in the final hour of descent, with their distinctive parallel folded ridgelines clearly visible from altitude.
