Sit on the Right side of the plane for the best views on flights from Keflavik to Paris. The right side misses the best of the Keflavik departure but delivers the iconic Paris approach view, which is the more visually rewarding payoff. Over the open North Atlantic and Scotland, neither side has a significant advantage, so the Paris arrival on the right side tips the balance.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Keflavik typically departs on runway 19 heading south or runway 10 heading east. On a southeasterly departure toward Europe, the left side faces northeast toward the Reykjanes Peninsula volcanic ridge and Reykjavik city across Faxaflói Bay. You get a clear view of the lava fields, geothermal steam plumes, and the capital's layout before turning southeast. Notable sights include: Reykjanes volcanic ridge with visible geothermal steam vents, Faxaflói Bay with Reykjavik visible across the water, Esja mountain massif north of Reykjavik, Blue Lagoon geothermal pools (distinctive milky-blue color in dark lava field).

When landing at Charles De Gaulle (CDG), sit on the Right side for the best views. CDG typically uses runways 26L/26R for westerly landings or 08L/08R for easterly approaches. On the standard westerly approach from the northeast, the right side faces south toward central Paris. You get a clear view of the Seine river bends, the Eiffel Tower, and the dense Haussmann grid of Paris as you descend through 5,000-8,000 feet on final. Notable sights include: Seine river with its distinctive meanders through Paris, Eiffel Tower visible as a thin spire, La Défense business district tower cluster west of the city, Bois de Boulogne as a large dark green rectangle.

The flight from Keflavik Nas (KEF) to Charles De Gaulle (CDG) takes Approximately 3 hours 15 minutes.

The route crosses the North Atlantic southeast of Iceland, then passes over the Scottish Highlands and northern England. On clear days the Outer Hebrides and Scottish west coast are visible. The route then crosses the English Channel near the Pas-de-Calais before entering French airspace over Picardy's flat agricultural plains on descent into CDG.
