It was not my original plan but after learning about the British Airways labor problems, I decided to come back from Singapore through Tokyo instead of London. I didn’t realize until thinking about it just now that I had traveled around the world this week. Here is a view of the path and distances (thanks to Great Circle Mapper). It is amazing that you could go more than 20,000 miles in about 40 hours (not counting ground time). In spite of occasional delays and aggravations, the travel system is a marvel that I greatly appreciate and do not take for granted.
