Sit on the Left side of the plane for the best views on flights from Newark to Seattle. Left side wins both the departure and arrival, and during the cruise the left side also faces generally south, giving better views of the northern Rockies and Cascades as the route tracks northwest across Montana and Idaho. The right side faces north into Canada with less dramatic terrain for much of the flight.

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 eastbound on 04L/04R. On the common westbound departure, a left-side seat gives you Manhattan's skyline and the Hudson River as you climb out and bank north. Even on eastbound departures, the left side captures the New York Harbor and Lower Manhattan as the aircraft turns northwest toward the route. Notable sights include: Manhattan skyline and Central Park, Hudson River, New York Harbor and Staten Island, Newark Bay and the Bayonne Bridge.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. SeaTac predominantly lands on runways 16L/16R heading southbound, meaning the aircraft approaches from the north over Puget Sound. A left-side seat on approach gives you Elliott Bay, downtown Seattle's skyline, and Mount Rainier to the southeast. The right side faces east toward the Cascade foothills but misses the dramatic water-and-city combination. Notable sights include: Elliott Bay and downtown Seattle skyline, Mount Rainier to the southeast, Puget Sound, Lake Washington.

The flight from Newark Liberty International (EWR) to Seattle Tacoma International (SEA) takes Approximately 5 hours 30 minutes to 6 hours.

The flight tracks northwest across Pennsylvania and the Great Lakes region, then over the northern Great Plains of Minnesota and South Dakota, crossing into Montana over the Missouri River drainage. The northern Rocky Mountains appear over central Montana, with the Bitterroot Range and Clearwater Mountains of Idaho visible before the aircraft descends toward the Cascades. The Columbia River Plateau and the volcanic peaks of the Cascades — including Mount Adams and Mount Rainier — are visible on the final approach into Seattle.
