BOAC: The Speedbird Routes Across the World, c.1950

The might of the empire spans the newsprint continents in this vintage route map of BOAC. Trunks routes out of London connect five continents, with a major trunk route crossing the Mediterranean at Malta, heading east to Cairo, Basra, Bahrain and Karachi, where the routes splits north along a Delhi-Calcutta-Rangoon-Bangkok axis, turning northeast to terminate at Hong Kong, while a second route reaches far southeast to Singapore, stopping intermittently at Surabaya, somewhat surprisingly, then into Antipodea at Darwin, finally reaching Sydney, where Tasman Empire Airways connects to Auckland. 

The next post will detail the African and North Atlantic routes.
