There is a great thread in World Discovery: Around the World in a Beechcraft Bonanza, or something like that. Order World Discovery by number of views, and it will be near the top. That will give you an exact route to fly. You don’t have to land at all the tiny airports in the thread A number of streamers are progressing on around the world journeys, and their routes are generally in their discords, in everything from a Cessna 172 to big jets. You’re bound to find one you like and be able to work off that.
