Sit on the Left side of the plane for the best views on flights from Austin to Seattle. Left side wins both ends of the flight. During cruise over the Pacific Northwest, the left side also tracks closer to the Cascades as the route arcs northwest, giving periodic views of volcanic peaks like Mount Shasta and the Oregon Cascades on clear days.

During takeoff from Austin Bergstrom International (AUS), sit on the Left side for the best views. ABIA's primary departure runway 17L/35R means northbound departures typically head northwest after takeoff. The left side gives you downtown Austin's skyline, the Colorado River, and Lake Travis as the aircraft banks north. Right side gets suburban sprawl. Notable sights include: Downtown Austin skyline, Colorado River/Town Lake, Lake Travis to the northwest, Barton Creek greenbelt.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. SeaTac's primary arrival runways 16L/16R bring aircraft in from the north heading south, meaning a left-side seat faces east toward the Cascades and Mount Rainier. You get a prolonged view of Rainier dominating the eastern horizon during the entire approach, plus Elliott Bay and downtown Seattle behind you to the north. Notable sights include: Mount Rainier (14,411 ft), Cascade Range, Elliott Bay and downtown Seattle, Puget Sound.
