Sit on the Left side of the plane for the best views on flights from Keflavik to Boston. Left side wins both ends of the flight. At departure you get the Reykjanes lava fields and the Reykjavik-Esja panorama as the plane climbs and turns southeast. At arrival you get the Boston skyline on approach. The mid-Atlantic crossing offers little on either side, so the bookend views are what matter.

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 view back over the Reykjanes Peninsula lava fields and toward Reykjavik. The right side faces open Atlantic immediately. As the aircraft turns southeast toward Boston, the left side briefly captures the Reykjavik skyline and Mount Esja across Faxafloi Bay. Notable sights include: Reykjanes Peninsula lava fields directly below, Mount Esja (914m) across Faxafloi Bay to the northeast, Reykjavik city and Hallgrimskirkja tower visible in the distance, Faxafloi Bay coastline.

When landing at General Edward Lawrence Logan International (BOS), sit on the Left side for the best views. Logan Airport sits on Boston Harbor, and aircraft typically approach from the northeast on runway 04R/04L or from the east on runway 09. A left-side seat on approach from the northeast gives you the Boston skyline, the Charles River, and Cambridge directly ahead and to the left. The right side faces the open Atlantic and harbor islands with less urban drama. Notable sights include: Boston downtown skyline with Prudential Tower and John Hancock Tower, Boston Harbor and its islands, Charles River and Cambridge below, Cape Ann coastline visible to the north on approach.

The flight from Keflavik Nas (KEF) to General Edward Lawrence Logan International (BOS) takes Approximately 6 hours 30 minutes to 7 hours.

The great circle route crosses the North Atlantic well south of Greenland, passing over open ocean for most of the flight. At roughly the midpoint you are over the central North Atlantic near 50-55N latitude. If routing takes you near the southern tip of Greenland you may glimpse its ice cap edge, but most KEF-BOS routings stay south of Greenland entirely. Nova Scotia and the Canadian Maritimes may be visible on the left side in the final 90 minutes before Boston descent.
