Why Fly to Phnom Penh?
Phnom Penh sits where the Mekong, Bassac, and Tonlé Sap rivers meet, a low-rise capital of French-colonial shophouses, gilded temples, and a hard, necessary history. Phnom Penh International Airport connects through Seoul, Tokyo, Hong Kong, Taipei, Singapore, and Doha — no US carrier flies nonstop, so routing choice matters more here than almost anywhere else on this list.
Royal Palace & Silver Pagoda
The working residence of Cambodia’s king, its gilded spires and the Silver Pagoda’s floor of 5,000 silver tiles make it the single most photographed site in the capital.
Tuol Sleng & the Killing Fields
A former high school turned Khmer Rouge prison, and the memorial site at Choeung Ek — sobering, essential context for understanding modern Cambodia, both a short tuk-tuk ride from downtown.
National Museum of Cambodia
A terracotta pavilion housing the world’s finest collection of Khmer sculpture, spanning the Angkor empire’s thousand-year run — the natural primer before visiting the temples themselves.
Sisowath Quay & Central Market
A riverside promenade of restaurants and bars facing the Tonlé Sap, minutes from Phsar Thmei’s Art Deco dome — one of the great covered markets of Southeast Asia.
Angkor Wat, a Short Flight Away
Siem Reap, gateway to the Angkor temple complex, is roughly a 45-minute domestic flight or a scenic bus ride from Phnom Penh — most itineraries pair both cities.

How to Find the Cheapest Phnom Penh Airfare
Practical strategies to reduce the cost of your Phnom Penh airline tickets from the USA.
Book 3–4 Months Ahead
Long-haul fares to PNH move the most in the shoulder months before the November–February high season. Booking three to four months out typically beats last-minute pricing by a wide margin.
Fly Midweek (Tue–Wed)
Tuesday and Wednesday departures on the major Asian carriers run 10–20% below Friday and Sunday fares — use flexible date search to see the full week.
Compare Seoul, Tokyo & Hong Kong Routings
Korean Air via Seoul, ANA via Tokyo, and Cathay Pacific via Hong Kong are usually the three cheapest paths from the US — fares between them can swing by hundreds of dollars by season.
Pair Phnom Penh with Siem Reap
A two-city Cambodia itinerary often beats a single-city fare on value — book into Phnom Penh and out of Siem Reap (or vice versa) to avoid backtracking for Angkor Wat.
Use Miles & Points
Star Alliance and Skyteam partner award seats to PNH via Seoul or Tokyo often beat cash fares on this long-haul route — check partner availability before paying cash.

Everything to Know About Cheap Flights to Phnom Penh
Flights to Phnom Penh from USA: What to Expect
Phnom Penh is Cambodia’s working capital rather than its postcard — a riverside city of temples, markets, and a modern history that demands to be reckoned with, plus the launch point for Angkor Wat. Every US itinerary connects at least once through Asia, so treat the hub choice — Seoul, Tokyo, Hong Kong, Taipei, Singapore, or Doha — as the biggest lever on both price and comfort. Use RedEye Fares to compare all routings side by side.
Phnom Penh Airfare: Budget Tips for US Travelers
Phnom Penh airfare from the USA typically runs $950–$1,650 round-trip in economy. Because this is a long-haul, multi-connection route, small differences in hub choice add up — compare at least three routings, book three to four months out, and set a fare alert for your travel window.
Phnom Penh Airline Tickets: Booking Advice
When comparing Phnom Penh airline tickets, check your connection time at the Asian hub — under 90 minutes is risky on a first international trip. A through-ticket on one alliance protects your onward leg if the first flight runs late. Book at least three months ahead for the best fares.
