Notable sights include: River Thames (meandering through London), City of London skyscrapers (distant but visible on horizon), Windsor Castle area (far southwest on clear days), Heathrow's own terminal buildings and runways.

The best window seat at Heathrow (LHR) depends on several factors: the typical runway used for your departure or arrival, the geographic features around London (mountains, coastlines, city skylines), weather conditions, and time of day. Morning and evening flights often offer the best lighting for scenic views.
