Sit on the Left side of the plane for the best views on flights from London to Pittsburgh (pennsylva). The Pittsburgh arrival on the left side is the highlight of this route — the three-river confluence and downtown skyline on approach is one of the most dramatic urban arrivals in the US. The left side also tracks the southern edge of the North Atlantic route, offering Greenland ice sheet views mid-flight. The right side takeoff view from Heathrow is good but shorter-lived.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow typically departs eastbound on runways 09L/09R, then aircraft turn northwest over London. The right side gives you a clear view south over the Thames valley, Windsor Castle, and the western London suburbs as you climb out. Left side faces north toward Slough and the M25 corridor, which is less distinctive. Notable sights include: Windsor Castle and Windsor Great Park, Thames river bends near Staines, Wembley Stadium arch visible to the northeast, Richmond Park.

When landing at Pittsburgh International (PIT), sit on the Left side for the best views. Pittsburgh International sits west of the city, and aircraft typically approach from the west on runway 28L/28R heading east. The left side on approach gives you a direct view of the Pittsburgh skyline at the confluence of the Allegheny, Monongahela, and Ohio rivers — the Golden Triangle is unmistakable. The right side faces south toward suburban sprawl with less visual interest. Notable sights include: Pittsburgh Golden Triangle (confluence of three rivers), Allegheny River valley, Monongahela River, Point State Park.

The flight from Heathrow (LHR) to Pittsburgh International (PIT) takes Approximately 8 to 9 hours westbound.

The flight tracks a great circle route northwestward over Ireland, then across the North Atlantic. Greenland's southern ice sheet and fjord coastline is visible mid-flight, followed by the Labrador coast of Canada, then Quebec and Ontario forests, Lake Erie's southern shoreline, and finally the Allegheny Plateau of western Pennsylvania on descent.
