Sit on the Right side of the plane for the best views on flights from Keflavik to Denver. While the left seat wins at departure for Iceland's volcanic scenery, the right seat at Denver arrival delivers one of the most spectacular approaches in North America with the full Front Range panorama. Over the ocean and Greenland the views are similar on both sides, so the Denver arrival tips the balance to the right seat overall.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Keflavik typically departs on runway 28 (heading west-northwest) or runway 10 (heading east). On a westbound departure climbing out over the Reykjanes Peninsula, the left side faces south toward the Atlantic and the volcanic lava fields of Reykjanes. On an eastbound departure, left side gives you Reykjavik city and Faxafloi Bay. Either way, left captures the most dramatic coastal and volcanic terrain. Notable sights include: Reykjanes lava fields, Faxafloi Bay, Mount Esja across the bay, Reykjavik city sprawl.

When landing at Denver International (DEN), sit on the Right side for the best views. Denver International sits east of the city, and aircraft typically approach from the east or northeast on runways aligned roughly north-south. On approach from the northeast, the right side faces west and southwest, giving a clear view of Denver's downtown skyline and the entire Front Range of the Rockies including Longs Peak, Mount Evans, and Pikes Peak stretching along the horizon. Notable sights include: Denver downtown skyline, Front Range Rocky Mountains, Longs Peak, Mount Evans.

The flight from Keflavik Nas (KEF) to Denver International (DEN) takes Approximately 8 to 9 hours.

The route tracks southwest over the North Atlantic, passing south of Greenland's ice sheet which may be visible on the left as a white mass near the horizon. The flight crosses the Davis Strait and then Labrador and Quebec's boreal forest, a vast dark green and lake-dotted landscape. Over Ontario and the Great Lakes, Lake Superior and Lake Michigan may be visible depending on exact routing. The flight then crosses the northern Great Plains of Minnesota, South Dakota, and Nebraska before descending into Colorado, with the transition from flat agricultural plains to the Rocky Mountain Front Range being the most dramatic visual moment of the entire route.
