Full route notes

Singapore to London via the northwest great circle crosses the Bay of Bengal, traverses the Indian subcontinent, continues over Pakistan and Iran's Zagros Mountains, cuts through Turkey near the Bosphorus, and sweeps across Europe's Alps before descending to Heathrow. The 13+ hour journey is a geography lesson at 40,000 feet.

One of the world's longest routes, SIN-LHR delivers an unbroken sequence of geographic highlights — Indian coastlines, Iranian mountains, and the Alps — all on the left side.

Actual paths can shift by 10-30 km due to airline routing, wind, weather, or air traffic control.

Timing, weather, and airline variation

Morning

Daytime over India offers optimal lighting for seeing the Bay of Bengal coastline and river deltas from the left.

Evening

Evening arrivals into London can catch the last Alpine light and a lit-up approach into Heathrow.

Weather

The Alps and Zagros Mountains are tall enough to poke above low cloud. The Bay of Bengal coast may be obscured by monsoon cloud June-September.

Airline routes

Different carriers may file slightly different paths, especially on long-haul routes, but the left side is the statistically stronger pick for the standard route.
