Sit on the Left side of the plane for the best views on flights from Keflavik to Pittsburgh (pennsylva). Left side dominates the outbound leg with Iceland's spectacular volcanic, glacial, and coastal scenery during the critical first 2–3 hours of flight. While right side offers good Appalachian and river views on descent into Pittsburgh, the takeoff experience from Keflavik is more visually distinctive and geologically dramatic.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Left side offers immediate views of Iceland's dramatic volcanic and glacial landscape. The departure path from Keflavik heads northeast over the Reykjanes Peninsula, then curves east across central Iceland, placing left-side passengers in direct view of the terrain. Notable sights include: Reykjanes Peninsula (volcanic lava fields and geothermal areas), Hengill geothermal region, Langjökull glacier (visible as white expanse in mid-distance during climb), Atlantic coastline of southwest Iceland.

When landing at Pittsburgh International (PIT), sit on the Right side for the best views. Right side provides excellent views during the descent approach into Pittsburgh. The standard descent path brings aircraft over the Appalachian highlands from the north and northwest, and right-side passengers see the rolling forested terrain, river valleys, and the Ohio River system that defines the Pittsburgh region. Notable sights include: Appalachian Mountains (ridge-and-valley topography), Ohio River and its confluence with the Allegheny and Monongahela rivers, Pittsburgh city skyline and downtown district, Allegheny County suburban sprawl.

The flight from Keflavik Nas (KEF) to Pittsburgh International (PIT) takes 5h 50m.

The flight crosses the North Atlantic at high altitude (typically 33,000–35,000 feet). Between Iceland and Greenland, passengers may glimpse the Denmark Strait and, on very clear days, the southern tip of Greenland's ice sheet on the horizon. The mid-Atlantic crossing itself offers little surface detail at cruise altitude. As the aircraft approaches North America (roughly over Labrador and Quebec), the boreal forest and lake-dotted Canadian Shield become visible. The descent into Pittsburgh crosses the Canadian Maritimes, New England, and the northern Appalachian region, with the Ohio River valley becoming prominent in the final 30 minutes.
