Luxury Vietnam & Cambodia Trip, Designed Exclusively for You

• Flight duration: The quoted 16–22 hours is a realistic door‑to‑door range that includes one or two layovers and transfer time; pure in‑air time can be shorter (e.g., ~14–16 hours) but connections add hours.
• Why times vary: Nonstop flights (mainly from SFO) cut travel time; most other U.S. gateways require a stop in East Asia or the Middle East, which increases total trip time.
• Stopover options: Common hubs are Tokyo (NRT/HND), Seoul (ICN), Taipei (TPE), Hong Kong (HKG), Singapore (SIN), Manila (MNL) and Middle East hubs like Doha (DOH) or Dubai (DXB). Choose a long layover if you want a short city visit.

Time difference and practical tips

• Time zones: Vietnam and Cambodia are both UTC+7. During U.S. Daylight Saving Time (March–November), the difference is +11 hours from Eastern (EDT), +12 from Central (CDT), +13 from Mountain (MDT), and +14 from Pacific (PDT). Outside DST add one hour.
• Jet‑lag tips: Sleep on the plane to match local night, stay hydrated, get sunlight on arrival, and plan a light first day (museum, gentle walk).
• Booking tips: If you prefer fewer hours in transit, look for SFO direct flights or one‑stop itineraries with short connections; if price is priority, compare one‑stop options via major Asian hubs.

Final recommendations:

• If minimizing travel time: Fly SFO → Ho Chi Minh nonstop when available.
• If you want a break en route: Pick a long layover in Tokyo, Seoul, or Singapore to stretch and see a city.
• If you tell me your departure city and preferred travel dates, I can suggest the best routing and realistic total travel times for your exact itinerary.
