Route notes
Why this routing works
This multi-stop itinerary is built as a straightforward out-and-back sequence: Columbus to Singapore, then Singapore to Los Angeles, and back to Columbus. With one primary long stop overseas and a short domestic stop on the return side, the routing keeps the trip structure simple while still adding a second city without requiring a separate ticket.
The longest flight segment is placed first, which can make timing easier if Singapore is the main stop. A 7-night stay gives the routing a clear center, while the 2-night stop in Los Angeles works as a brief break before the final leg home. For travelers departing in September, this is a compact multi-stop plan that fits into roughly a one-week framework as listed.
Because this is ticketed as an economy multi-stop itinerary rather than separate one-way flights, the route is organized around a fixed city sequence: Columbus, Singapore, Los Angeles, then Columbus again. That can be useful for travelers who want one booking covering the full chain of flights and a defined stop order from departure through return.
