Route notes
Why this routing works
This 3-week multi-stop itinerary is built as a one-direction routing from Chicago across East Asia into Southeast Asia, then back to Chicago from Bali. The sequence keeps the trip moving steadily southward after Tokyo and Seoul, which helps avoid backtracking and makes the stop pattern easier to ticket on a single multi-city plan.
Starting in Tokyo, then continuing to Seoul and Hong Kong, the route groups the northern Asia segments first before shifting into Ho Chi Minh City, Bangkok, and Denpasar Bali. That progression is practical for travelers who want several short-to-medium flight connections within one ticket rather than a series of separate one-way bookings.
With six stops between departure and return, this is a dense schedule for a 3-week trip, so timing at each city matters. In economy, a route like this works best when the stop order is set early and the onward flights are coordinated as one package, especially for a June departure window when the whole itinerary needs to fit a fixed overall duration.
