Sit on the Right side of the plane for the best views on flights from Las Vegas to London. The takeoff view from the right seat over the Las Vegas Strip, Red Rock Canyon, and the Spring Mountains is genuinely spectacular and hard to beat. The landing approach on the left is good but London under typical overcast is less dramatic. Right side also captures the Colorado Rockies during the early climb-out phase as the aircraft heads northeast, adding another major visual payoff. The right seat wins on total scenic value across the flight.

During takeoff from Mc Carran International (LAS), sit on the Right side for the best views. Departing Las Vegas, most flights use runway 26L/26R heading west-northwest or 19L/19R heading south. On a northbound transatlantic routing, aircraft typically turn northeast after departure. A right-side seat gives you the Las Vegas Strip laid out below, then the Spring Mountains and Red Rock Canyon escarpment to the west as you climb out. Left side faces east toward the flat Mojave and Henderson sprawl, which is far less dramatic. Notable sights include: The Las Vegas Strip (visible as a dense cluster of hotel towers), Red Rock Canyon escarpment (the sharp red sandstone ridge 15 miles west), Spring Mountains/Charleston Peak (11,918 ft, snow-capped in cooler months), Lake Mead (visible to the northeast as a blue reservoir against brown desert as the aircraft turns).

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's dominant runway orientation is 27L/27R, meaning aircraft approach from the east heading west. On this transatlantic arrival, the aircraft descends over central London on the ILS approach. A left-side seat faces south, giving you the Thames snaking through central London, the City skyline, and landmarks across south London. Right side faces north toward the less iconic suburbs of Ealing and Hounslow. Notable sights include: The River Thames (clearly visible as a wide silver ribbon curving through the city), The City of London/Canary Wharf skyline (cluster of towers visible to the southeast), Windsor Castle and Windsor Great Park (visible to the south-southwest on final approach), Wembley Stadium (distinctive arch visible to the north on left-side seats — actually this is right side, correcting: Windsor Castle is the key left-side landmark on approach).

The flight from Mc Carran International (LAS) to Heathrow (LHR) takes Approximately 10 to 11 hours.

After departing Las Vegas the route tracks northeast over the Colorado Rockies (visible from both sides in the first hour), then across the Great Plains, the Great Lakes region (Lake Michigan or Lake Superior may be visible depending on exact routing), then the Canadian Maritime provinces or Newfoundland, followed by the North Atlantic. At cruise altitude over the Atlantic there is little to see except ocean and occasional sea ice near Greenland on more northerly routings. The route may pass south of Greenland's ice sheet, which appears as a vast white plateau on the horizon if routing goes far enough north. Landfall over Ireland or southwest England precedes the London descent.
