Halfway Between London and Hong Kong: The Bay of Bengal

There's no land at the exact midpoint. The geodesic midpoint falls in the Bay of Bengal, near the Andaman and Nicobar Islands (Indian territory).

• Coordinates (approx): 10°N, 92°E
• Distance from London: ~4,850 km (3,000 mi)
• Distance to Hong Kong: ~4,850 km

The Andamans are the nearest land—Port Blair is ~300 km north. The midpoint is open ocean, ~4,000 m deep.

Flights London–Hong Kong (e.g., BA, Cathay, Virgin) typically route over Russia/Kazakhstan/China (north) or Middle East/India (south)—neither passes the true midpoint.
