Administrative Note

U.S. citizens can obtain a visa on arrival (30 days, $30 USD) or apply for an e-visa online in advance. Passport must be valid 6+ months. No vaccinations required but recommended: Hepatitis A/B, Typhoid. Flight costs vary ($700–$2,000+ round-trip depending on season, routing and booking time). No direct flights; all involve 1–2 stops. Main arrival airport: Siem Reap–Angkor (SAI). Verify travel advisories, visa rules, airspace status and entry requirements via official sources or Legend Travel Group support.

Recommended Safe Routes

To avoid Middle East airspace and carriers (such as those via Dubai, Doha or Abu Dhabi), prioritise routings through Europe (e.g., via Paris, Frankfurt, Amsterdam, London) then onward via Asia, or direct Asian connections via East Asia (e.g., via Seoul, Tokyo, Taipei, Hong Kong). These options minimise exposure to affected regions.

• Via Europe + Asia — Example: IAD → European hub (Air France, Lufthansa, KLM, British Airways) → Bangkok (BKK) or Singapore (SIN) → Siem Reap (SAI) with Bangkok Airways or other regional carriers.
• Via East Asia — Strong options: IAD → Seoul (ICN) with Korean Air or Asiana → Siem Reap; or via Tokyo (NRT/HND) with ANA/JAL connections; via Taipei (TPE) with EVA Air or STARLUX.
• Flight Time — No direct flights; total duration typically 20–28 hours including layovers (fastest safe connections around 22–25 hours).
• Best Airlines for Avoidance — Korean Air, EVA Air, ANA, JAL, Air France/KLM, Lufthansa, Singapore Airlines (for segments). These provide reliable service without transiting restricted Middle East hubs.
• Accessibility from Washington DC — Depart primarily from IAD (better international options); DCA has fewer long-haul choices. Internal Cambodia transfers from Phnom Penh or direct to SAI.

Key Tips for Booking Safe Routes

• Use Google Flights or Skyscanner with filters to exclude specific airlines/hubs; manually check routings.
• Book 2–4 months ahead; mid-week departures often cheaper.
• Monitor airspace updates — current situations may cause rerouting even on non-Middle East paths.
• Consider flexible dates and multi-city options (e.g., arrive Siem Reap, depart Phnom Penh).

Visa Options

• Visa on Arrival — Available at Siem Reap Airport ($30 USD cash, 30 days, single entry). Bring passport photo if possible.
• E-Visa — Apply online in advance (around $36–$40, 30 days). Faster processing and recommended for peace of mind.
• Passport: Valid 6+ months beyond stay with at least one blank page.

General Advice:

• No yellow fever requirement unless from endemic area.
• Respect local customs: Modest dress at temples (shoulders/knees covered); remove shoes when entering sacred sites.
