If you'd like a quick guide, we've compiled all the relevant times, distances, and Airship attributes in shared spreadsheet for everyone! It also includes a Route Planner to find the most efficient path across up to 5 islands and Rigging advice for keeping to a daily schedule

Since the distance and travel time don't have an exact relationship on the player side, estimating the true coordinates can only get as close as the real travel times and distances you used as inputs (and usually ends up going in very reasonable-looking, but misleading loops very quickly)
