DEN → KEF
Which side of the plane to sit from Denver International Airport (Denver) to Keflavik International Airport (Keflavik)?
Left Side of the Plane
The left side is superior for this trans-polar route because it faces north, providing the best vantage point for the Aurora Borealis and the most dramatic sections of the Greenland ice cap and Baffin Island peaks.
Search flights from DEN to KEF
Northern Front Range
Spectacular views of the Colorado Rockies and Longs Peak immediately after departing Denver.
Baffin Island
Deep fjords and the massive, rugged mountain ranges of the Canadian Arctic wilderness.
Greenland Ice Sheet
Crossing the heart of the world's second-largest ice body, featuring crevasses and meltwater lakes.
Aurora Borealis
On overnight flights, the north-facing windows offer a front-row seat to the Northern Lights.
North Atlantic Icebergs
Spotting massive chunks of ice breaking off the Greenland coast into the dark ocean waters.
Choose the left side (Port) for the best chance of seeing the Aurora Borealis during the middle 4-5 hours of the flight when passing through the auroral oval. Use a blanket to cover your head and the window to block cabin light for better night visibility. This side also avoids direct glare during the morning arrival in Iceland.

High Plains
The geometric patterns of the American Midwest and the transition into the Canadian prairies.
Hudson Bay
A vast expanse of water or ice depending on the season, marking the entry into the deep north.
Southern Greenland Coast
Stunning views of the jagged peaks near Prince Christian Sound if the route tracks south.
Reykjanes Peninsula
A close-up view of the volcanic craters and fresh lava fields of Iceland during the final descent.
Geothermal Steam
Visible plumes from power plants and the Blue Lagoon area as the plane nears Keflavik.
The right side (Starboard) is ideal for watching the sunrise over the North Atlantic as you approach Iceland. During the final 20 minutes of flight, this side often provides a clearer view of the Reykjanes Peninsula's volcanic activity and the rugged coastline. Be prepared for high-contrast light as the sun rises on this side of the aircraft.
