Sit on the Right side of the plane for the best views on flights from London to Houston. The right side wins overall primarily for the London departure views, which are genuinely spectacular and hard to beat. The mid-Atlantic and Canadian overfly offer limited differentiation by side, and the Houston approach on the left is good but over flat terrain. The London departure on the right is the highlight of the flight.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures on the eastbound runways (09L/09R) head east over London before turning northwest. The right side gives you a sweeping view over central London — the Thames snaking through the city, the City of London skyline, and Canary Wharf's towers are all clearly visible during climb-out. If departing westbound (27L/27R), the right side looks south over Windsor Great Park and the Thames valley. Notable sights include: River Thames bends through central London, Canary Wharf cluster, Windsor Castle and Great Park (westbound departures), M25 orbital motorway ring.

When landing at George Bush Intcntl Houston (IAH), sit on the Left side for the best views. IAH sits north of Houston and aircraft typically approach from the north or northeast on runways 26L/26R or 27. On these approaches the left side looks south over the Houston metro sprawl, with the downtown skyline visible in the distance and the ship channel and refineries to the southeast. This is the more visually interesting side compared to flat Texas farmland on the right. Notable sights include: Houston downtown skyline, Houston Ship Channel and refinery complex, Lake Houston to the northeast, Interstate highway grid converging on the city.

The flight from Heathrow (LHR) to George Bush Intcntl Houston (IAH) takes Approximately 10 to 11 hours.

The route tracks northwest over Ireland, then across the North Atlantic via the North Atlantic Tracks, passing south of Greenland and Iceland. Over Canada it crosses Newfoundland and Labrador, then tracks southwest over Quebec and Ontario before entering US airspace over the Great Lakes region or Ohio, continuing south over the Mississippi basin toward Texas. Mid-flight features include the Labrador coastline, occasional sea ice near Greenland, and the vast boreal forest of Quebec visible on clear days.
