Sit on the Left side of the plane for the best views on flights from London to Cincinnati. The left side wins overall because while the right side has the better London departure view, the left side tracks the southern edge of Greenland's ice sheet during the transatlantic crossing, offers glimpses of Newfoundland's rugged coastline, and delivers the Ohio River valley on arrival. The Greenland ice cap view alone — a vast white expanse broken by nunataks and outlet glaciers — is one of the most dramatic sights on any North Atlantic route.

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 toward the Atlantic. A right-side seat gives you views over central London as the aircraft banks — you can pick out the Thames snaking through the city, the dense urban grid of West London, and Windsor Castle and its Great Park to the southwest before the city gives way to the Home Counties. Notable sights include: River Thames through central London, Windsor Castle and Great Park, Wembley Stadium arch, Chiltern Hills escarpment to the northwest.

When landing at Cincinnati Northern Kentucky International (CVG), sit on the Left side for the best views. CVG sits just south of the Ohio River, and aircraft typically approach from the east or northeast on runways oriented roughly east-west. A left-side seat on approach gives you a clear view of the Ohio River valley, the Cincinnati skyline across the river in Ohio, and the Kentucky hills rolling away to the south. Notable sights include: Ohio River and its broad valley, Cincinnati downtown skyline, Kentucky bluegrass farmland patchwork, Greater Cincinnati suburban sprawl.

The flight from Heathrow (LHR) to Cincinnati Northern Kentucky International (CVG) takes Approximately 9 to 9.5 hours.

The flight follows a great circle route arcing northwest over Ireland and the Celtic Sea, then across the North Atlantic passing south of Iceland. The left side gets views of the southern tip of Greenland's ice sheet and fjord coastline around Narsarsuaq. The route then crosses southern Labrador and Quebec, where the Canadian Shield's lake-studded boreal forest is visible for hundreds of miles. Descending into the US, the Appalachian ridges of Pennsylvania and Ohio appear as parallel corrugated folds before the terrain flattens into the Ohio River basin.
