Suez Canal vs Cape of Good Hope (Asia – Europe)
Estimated distance and transit for the same voyage via the Suez Canal and via the Cape of Good Hope. The Cape routing avoids the Red Sea but adds distance, fuel and time.

Distances are the sum of great-circle legs between waypoints along the usual sea lanes, through the relevant straits and canals, rounded to the nearest 10 nautical miles. Transit ranges assume a typical service speed of 16–18 knots plus time for intermediate port calls and canal transits; transshipment adds several days for the connection at the hub. Figures are estimates for planning and comparison, not carrier schedules.
Since early 2024, attacks on merchant ships around Bab-el-Mandeb led most carriers to divert Asia–Europe, Asia–Mediterranean and some Asia–US East Coast services around the Cape of Good Hope, adding roughly 3,000–3,500 nm and about 7–14 days depending on the route and service speed. Some carriers have since tested or resumed Suez transits on selected services. Routing is decided per service by each carrier, so check the current routing when you book.
