Lucknow to London is 4,433 miles (7,134 km), a flight of about 8 hours 45 minutes.
The London approach significantly outscores the Lucknow departure. While Lucknow offers modest views of the Indo-Gangetic Plain and river system, London's descent provides dramatic urban-to-rural contrast, the Thames estuary's distinctive geography, and Greater London's sprawling development. The right side captures the most visually varied and recognizable landmarks of the entire flight, particularly during the final 30 minutes of descent. The left side's takeoff views are relatively flat and repetitive.
Flight Path
The flight path crosses the Himalayas' southern foothills (Hindu Kush and Pamir ranges visible from cruise altitude), the Caspian Sea's eastern shore, the Caucasus Mountains, Eastern Europe's plains, and the Alps before descending into the Thames Valley. Cruise altitude provides views of Afghanistan's Hindu Kush, the Caspian Sea's northern coast, southern Russia's steppes, and Central European terrain. The Alps appear as a dramatic mountain barrier approximately 90 minutes before London arrival.
