Flight Deals from Washington to Singapore from $620

The flight from Washington to Singapore is about 9,660 miles. There is no scheduled nonstop service on this route, so the journey requires a connection.

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.

There are no non-stop flights from Washington to Singapore. The shortest connecting routing is on Singapore Airlines via Zurich, a 22-hour journey made up of a 485-minute (8h 5m) first leg on Swiss, a 75-minute (1h 15m) layover, and a 760-minute (12h 40m) second leg on Singapore Airlines. Qatar Airways via Doha is a close second at 22h 10m.

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.

From Singapore Changi Airport to the city center, you have several solid options: taxis and ride-hailing apps like Grab, Gojek, Zig, and Tada offer the fastest point-to-point service at about 20 to 30 minutes for roughly $18 to $38 SGD; the MRT train is the most affordable and widely used choice, taking about 33 minutes to City Hall for under $3 SGD with a simple transfer at Tanah Merah; public bus service 36 costs under $2 SGD but takes about an hour; and a dedicated City Shuttle serves many downtown hotels for around $9 to $10 SGD per adult. The MRT is the most-used option because it's cheap, frequent, and reliable, though taxis and ride-hailing are better if you have lots of luggage or are heading to a less central address. Car rentals are not a practical airport-to-city transfer for most travelers, as driving and parking in central Singapore are generally unnecessary given the excellent public transit.

There are no nonstop red-eye flights from Washington to Singapore, but connecting itineraries with an overnight long leg do operate. United offers a routing through San Francisco departing 22:40 and arriving 06:15, while Turkish Airlines connects via Istanbul departing 17:50 and arriving 09:30. EVA Air also runs an overnight leg through Taipei departing 01:15 and arriving 05:10, and Etihad connects via Abu Dhabi departing 15:10 and arriving 12:15.

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.

There is no nonstop service from Washington to Singapore, so travelers connect through hubs like Zurich, Doha, Taipei, Dubai, San Francisco, or Abu Dhabi. Qatar Airways offers the most frequent one-stop option via Doha with 11 daily connections, while United Airlines operates several routings through San Francisco and Tokyo Haneda. Singapore Airlines links with Swiss via Zurich for the fastest overall journey at 22 hours, and EVA Air, Emirates, Etihad, Turkish Airlines, and Ethiopian Airlines also serve the route with single daily connections. Alliances on this route include Star Alliance (Singapore Airlines, Swiss, EVA Air, United, All Nippon Airways, Turkish, Ethiopian) and oneworld (Qatar Airways), with Emirates and Etihad operating independently.

Singapore has one main international airport, Changi, which serves all commercial flights for the city. It is about 20 km east of downtown and connects directly to major attractions by MRT.

From downtown Washington, D.C., the quickest and most popular way to reach Washington Dulles International Airport is the Metro’s Silver Line, which runs directly from the city center to the airport terminal in about 47 minutes at a low fare. Public bus options include the Metrobus 5A and the Silver Line Express shuttle, which are economical but involve transfers and longer travel times. Ride-share services such as Uber and Lyft, along with taxis and private car services, offer door-to-door convenience at a higher cost, typically taking 30 to 60 minutes depending on traffic. Driving yourself is possible with on-site parking, though it adds the expense of daily rates and the hassle of navigating traffic.

There is no nonstop service from Washington to Singapore, so travelers connect, typically on a single long-haul leg. Qatar Airways operates the most connecting flights, using the Airbus A350-900 or Boeing 777-300ER on the long leg via Doha, while United connects via San Francisco or Tokyo with the Boeing 787-9 or Boeing 777 family. Other carriers such as Turkish Airlines, Singapore Airlines, Emirates, and EVA Air also serve the route with aircraft like the Airbus A350-900, Boeing 777-300ER, or Boeing 787-9.

Methodology

Aircraft types 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
