Sit on the Left side of the plane for the best views on flights from Keflavik to New York. Left wins both ends of the flight. The Reykjanes lava fields and Faxaflói Bay at departure are genuinely dramatic, and the Jamaica Bay and Manhattan approach at arrival is one of the more recognizable urban approaches in aviation. Right side sees open North Atlantic for most of the flight with little to distinguish it.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Keflavik typically departs eastward on runway 10, so the left (north) side gives you a clear view back over the Reykjanes Peninsula lava fields and Faxaflói Bay. You'll see the dramatic contrast between the dark volcanic terrain and the North Atlantic as the aircraft climbs out. Notable sights include: Reykjanes Peninsula lava fields, Faxaflói Bay, Mount Esja across the bay to the northeast, Reykjavik city lights if departing in low light.

When landing at John F Kennedy International (JFK), sit on the Left side for the best views. JFK typically lands on runway 31L or 22L from the east, meaning the left side faces south and southwest toward Jamaica Bay, the Rockaway Peninsula, and the Manhattan skyline in the distance. This is consistently the more scenic approach side with recognizable New York geography. Notable sights include: Jamaica Bay and its barrier islands, Rockaway Peninsula, Manhattan skyline on the distant horizon to the northwest, Coney Island shoreline.

The flight from Keflavik Nas (KEF) to John F Kennedy International (JFK) takes Approximately 6 to 7 hours.

The great circle route crosses the North Atlantic, passing south of Greenland's tip near Cape Farewell, then over the Labrador Sea and the coast of Nova Scotia or Newfoundland depending on winds and routing. Passengers may see sea ice or icebergs near the Greenland coast at altitude, and the Canadian Maritime coastline with its bays and inlets becomes visible in the descent phase. The mid-Atlantic portion is open ocean with no land features.
