Route notes
Why this routing works
This itinerary is structured as an open-jaw start followed by a continuous westbound chain across Asia and the Pacific. The ticket is listed from New York City, but Phnom Penh is reached overland, which creates a gap before the first flown segment and gives flexibility on how the trip begins. From there, the routing tightens into short regional hops through Hanoi and Bangkok before the longer transpacific sequence via Tokyo and onward to Hawaii and South Florida.
The sequencing keeps the Asian stops grouped together before the Pacific crossing, which is a practical way to reduce backtracking on a 4-week trip. Bangkok and Tokyo have short stays of 3 and 2 nights respectively, so connection timing matters more than adding extra sectors. Lihue then works as the final stop before the mainland US endpoint in Fort Lauderdale, separating the long-haul Pacific flying from the last domestic leg.
Because this is a business-class multi-stop itinerary, the main value is in packaging several long and medium-haul segments onto one ticket while preserving a clear directional flow. January departure timing places the trip in the Jan-Mar season, which is useful when pricing and availability are being compared across multiple transpacific and regional segments. Overall, this is a compact 4-week routing built around efficient stop order rather than return-point symmetry.
