Sit on the Right side of the plane for the best views on flights from Montreal to Keflavik. Right seats capture the most dramatic geography: the Laurentian Mountains on departure (though modest), and the striking volcanic landscape of Reykjanes Peninsula on arrival. The landing view is particularly distinctive—the dark lava fields are unmistakable and visually compelling.

During takeoff from Montreal International Dorval (YUL), sit on the Left side for the best views. Montreal typically departs westbound on Runway 06L/24R or eastbound on 06R/24L. For northbound routing to Iceland, westbound departure (Runway 24L/R) is standard. Left seats face north across the St. Lawrence River valley and Laurentian Mountains, offering the best view of the climb corridor. Notable sights include: St. Lawrence River (flowing east-west below), Laurentian Mountains (northern horizon, part of Canadian Shield), Montreal urban sprawl (receding southward), Île Perrot (visible in river to the west).

When landing at Keflavik Nas (KEF), sit on the Right side for the best views. Keflavik typically uses Runway 02/20. Approach from the south (Runway 02) is standard for transatlantic arrivals. Right seats face west across the Reykjanes Peninsula and the Atlantic approach corridor, capturing the volcanic landscape and coastal features during descent. Notable sights include: Reykjanes Peninsula (volcanic plateau with dark lava fields), Atlantic Ocean (to the west and north), Keflavik town and airport infrastructure (on the peninsula), geothermal areas with steam vents (visible as white plumes in winter/cool conditions).

The flight from Montreal International Dorval (YUL) to Keflavik Nas (KEF) takes Approximately 5 hours 15 minutes to 5 hours 45 minutes.

The flight path crosses the Atlantic at roughly 55°N latitude. Notable features include: the Labrador Sea (dark, cold water with occasional icebergs in winter/spring), the Mid-Atlantic Ridge system (not visible from altitude but the flight passes over it), and the transition from North American continental air masses to the North Atlantic's maritime climate. Around 2-3 hours into the flight, the Canadian Maritime provinces (Nova Scotia, Newfoundland) recede to the southwest. The final 2 hours approach Iceland with the Denmark Strait visible to the left (west), separating Greenland from Iceland. Greenland's ice sheet may be visible on the western horizon in clear conditions.
