Sit on the Left side of the plane for the best views on flights from Keflavik to Portland. While takeoff from KEF favors right seats, the landing approach into PDX strongly favors left seats with Mount Hood and the Cascade Range as dominant visual features. Most passengers will spend more time on descent than climb-out, making left the better overall choice.

During takeoff from Keflavik Nas (KEF), sit on the Right side for the best views. KEF typically departs runway 02 (northbound) or 20 (southbound). Right seats offer views of Iceland's southwestern coast, including the dramatic Reykjanes Peninsula lava fields and the Atlantic coastline. Left seats face inland toward less distinctive terrain. Notable sights include: Reykjanes Peninsula (dark basalt lava fields), Atlantic Ocean to the west, Fagradalsfjall volcanic region, Grindavík geothermal area.

When landing at Portland International (PDX), sit on the Left side for the best views. PDX typically lands runway 28L/28R (westbound) or 10L/10R (eastbound). Westbound approaches (most common) give left seats excellent views of the Cascade Range, Mount Hood, and the Columbia River Gorge. Right seats face the Willamette Valley, which is less visually distinctive. Notable sights include: Mount Hood (11,240 ft, snow-capped), Cascade Range, Columbia River Gorge, Willamette Valley.
