Claude builds a 3D planner for multi-stop flight routes
in was used to build a web tool that draws multi-city flight routes on a 3D globe. After cities are selected in order, it displays the route, total distance, travel time, and layover duration. The full tool was built with Claude’s help, with Claude handling the and WebGL work that was expected to take weeks to learn and code alone.
A sample New York → Dubai → New Delhi → Mumbai route measured 14,614 km and about 35 hours, including a four-hour layover. Airport-code entry, airline filters, and fare estimates are possible next rather than current .
Key points
- Selecting several cities draws the complete route on an interactive 3D globe.
- The tool shows total distance, travel time, and time spent on layovers.
- Claude handled the and WebGL work that was expected to take weeks to learn independently.
- The example four-city route covered 14,614 km in about 35 hours, including a four-hour layover.
- Airport codes, airline filters, and fare estimates are ideas for future additions.
