Flight Deals from Singapore to Phnom Penh from $128

The flight from Singapore to Phnom Penh is about 695 miles. The typical nonstop flight time is 2 hours, with the return leg taking about 2 hours 15 minutes.

Methodology

Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

Singapore Airlines and Emirates are currently scheduled nonstop from Singapore to Phnom Penh, with four weekly flights between them. Singapore Airlines operates three flights on Sundays only, while Emirates operates one Sunday flight. Neither carrier flies daily on this route.

Methodology

Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

Getting into Phnom Penh from Techo International Airport is straightforward, with taxis, tuk-tuks, and the dedicated Airport Express Bus being the main options. The Airport Express Bus is the most budget-friendly and heavily used choice for travelers, running every 10–20 minutes and costing just 1,500 KHR (about $0.37 USD), connecting the airport to the Kouch Cannon Roundabout Bus Station near the city center. Ride-hailing apps like Grab, PassApp, Move, and WowNow are also popular and widely used, typically costing around $15–$20 for a taxi or tuk-tuk into town. Pre-booked private transfers and car rentals are available at the airport as well, offering a more comfortable but pricier alternative. Taxis and ride-hailing services are generally the fastest way to reach the city center, with the trip taking roughly 50 minutes depending on traffic.

There are no nonstop red-eye flights from Singapore to Phnom Penh, but connecting overnight itineraries do exist. China Southern operates a long overnight leg from Singapore to Guangzhou departing at 3:55 AM and arriving at 7:55 AM, then connecting on to Phnom Penh, and Xiamen Air runs a similar leg via Xiamen departing 3:00 AM and arriving 7:05 AM.

Methodology

Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

Singapore Airlines and Emirates are the airlines currently scheduled nonstop from Singapore to Phnom Penh. Singapore Airlines operates three weekly flights on Sundays, while Emirates operates one weekly flight on Sundays. Both carriers are scheduled on a limited basis rather than daily, reflecting the current week's schedule.

Methodology

Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

From Singapore city center, the MRT is the most popular and efficient way to reach Changi Airport: take the East-West Line to Tanah Merah, then transfer to the Changi Airport branch train, which arrives directly at Terminals 2 and 3 in about 33 minutes for under $3 SGD. Public bus service 36 also runs from the city to the airport terminals for a similarly low fare, though it takes around an hour. Taxis and ride-hailing services like Grab offer door-to-door convenience with a 20–30 minute drive and metered fares typically between $18 and $38 SGD, while the City Shuttle provides fixed-price transfers to most downtown hotels. Driving and parking at Changi are available, but most travelers opt for the MRT or a taxi for speed and simplicity.
