How long does it take cargo ship to come from south Korea to England?

Answer 1

In most cases, there's no direct service. You'd have to take a ship from NYC through the Panama Canal to the U.S. west coast, then go across the Pacific with a possible stop in Hawaii. Since this would involve combining the offerings of various cruise lines, or possibly shipping companies that also carry a limited number of passengers, the total time might be quite variable. A bare minimum would be about 12-14 days if everything connected just right, but reality would almost certainly be much longer -- due to stopovers. Some cruise lines (e.g., Cunard) offer round-the-world cruises that might cover that particular routing. It's often possible to book shorter segments such as the trip you are describing. However, availability, routing, and travel times again would be highly variable.
