Sit on the Right side of the plane for the best views on flights from Newark to Seattle. The Seattle arrival on the right side is the single best view of the flight — Elliott Bay, the downtown skyline, and Mount Rainier on final approach is hard to beat. The left side wins at takeoff for Manhattan, but the right side arrival into BFI is more dramatic and consistent. Across the cruise portion over the northern Rockies and Cascades, right side also tends to offer better mountain views as the route tracks northwest.

During takeoff from Newark Liberty International (EWR), sit on the Left side for the best views. EWR typically departs westbound on runway 22L/22R or northbound on runway 4L/4R. On a westbound departure, the left side gives you Manhattan's skyline receding behind you, plus the Hudson River and Upper New York Bay. On a northbound departure, left side still captures the Manhattan skyline across the Hudson as you climb out over New Jersey. Notable sights include: Manhattan skyline, Hudson River, Upper New York Bay, Verrazano-Narrows Bridge.

When landing at Boeing Fld King Co International (BFI), sit on the Right side for the best views. BFI sits just south of downtown Seattle, and aircraft typically approach from the south or southeast on runway 13R/13L. The right side on final approach gives you Elliott Bay, the Seattle waterfront, and the downtown skyline, plus Lake Washington to the east. This is the money shot for Seattle arrivals. Notable sights include: Elliott Bay, Seattle downtown skyline, Lake Washington, Mount Rainier (distant to southeast).

The flight from Newark Liberty International (EWR) to Boeing Fld King Co International (BFI) takes Approximately 5 hours 30 minutes to 6 hours.

The route tracks northwest over Pennsylvania, then across the Great Lakes region or southern Ontario, then over the northern Great Plains of Minnesota and the Dakotas. Over Montana and Idaho the northern Rocky Mountains become prominent — the Bitterroot Range and the Clearwater Mountains are visible below. As the flight descends toward Seattle, the Cascade Range comes into view with volcanic peaks including Mount Adams and Mount Rainier visible to the south, and the Columbia River Plateau transitions to the forested western slopes of the Cascades.
