Route notes
Why this routing works
This itinerary is built as a three-stop loop from Washington DC through South Asia and East Asia before returning home. The sequencing keeps the trip moving in one direction: a short first stop in New Delhi, a longer middle stay in Colombo, then a final stop in Seoul before the transpacific return to Washington DC.
At three weeks total, the split of 4 nights in New Delhi, 12 nights in Colombo, and 4 nights in Seoul makes the Colombo segment the anchor of the trip. That structure suits travelers who want one primary stay with two shorter city stops built into the same ticket rather than separate one-way bookings.
Because this is sold as a multi-stop itinerary in economy, the value is in combining long-haul and regional flights into one coordinated route. For January departures, keeping these stops on a single ticket can simplify the overall timing and reduce the need to piece together separate segments across multiple regions.
