BA54 distance and great-circle path
BA54 covers 9,074 km, or 5,639 miles. That makes it an ultra-long-haul flight, near the limit of what most twinjets can fly non-stop. Of the 271 routes we track, it ranks 87 by distance.
This flight changes hemisphere. Johannesburg sits in the southern half of the world and London in the northern, so the 9,074 km run north lands in the opposite season to the one it left. Watches move 1 hour back between the two gates. It links South Africa with United Kingdom.
