Sit on the Left side of the plane for the best views on flights from Nice to Seattle. The right side wins at takeoff for the Côte d'Azur coastal panorama, but the left side delivers the superior Mount Rainier arrival view, which is genuinely one of the great airport approaches in the world. Across the full flight, the left side also tracks the Canadian Rockies during the mid-flight segment over Alberta and British Columbia, making it the stronger overall choice.

During takeoff from Cote D Azur (NCE), sit on the Right side for the best views. Nice's runways 04L/04R point northeast over the sea, so a right-side seat looks back southwest along the Côte d'Azur coastline toward Cannes and the Esterel massif. Left side faces inland toward the Alps immediately, which is dramatic but the coastal panorama on the right is more expansive during the initial climb. Notable sights include: Monaco and Cap Ferrat headland to the east, Cannes and Lerins Islands to the southwest, Esterel red volcanic massif, Nice city grid and the Baie des Anges.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. Seattle-Tacoma typically uses runways 16L/16R for southbound arrivals, meaning the approach comes from the north heading south. A left-side seat on this approach faces east toward the Cascade Range, with Mount Rainier dominating the view — one of the most visually striking airport approaches in North America. Right side looks west over Puget Sound and the Olympic Peninsula, which is scenic but less dramatic. Notable sights include: Mount Rainier (14,411 ft, snow-capped, dominant), Cascade Range ridgeline, Lake Washington and Seattle city skyline to the north, Puget Sound.

The flight from Cote D Azur (NCE) to Seattle Tacoma International (SEA) takes Approximately 11 to 12 hours nonstop, typically routing over the Alps, central Europe, Greenland or Iceland, then across Canada and the Pacific Northwest.

Swiss and Austrian Alps during initial climb-out phase, then the North Atlantic crossing near southern Greenland with potential iceberg and ice sheet views, followed by the Canadian Arctic and sub-Arctic boreal forest of Quebec and Ontario, then the Canadian Rockies over Alberta and British Columbia including the Columbia Icefield area, and finally the Cascade Range on descent into Seattle
