Singapore sits at the crossroads of Asia, operates one of the world's finest airports, and offers a remarkable blend of cultures, cuisine, and modern architecture. Cheap flights to Singapore from the US require planning — the city-state is roughly 9,000 miles from the West Coast — but competitive fares are available year-round with the right approach.

Singapore's airport: Changi (SIN)
Singapore has one primary international airport:
- Singapore Changi Airport (SIN) — Consistently rated the world's best airport, Changi is the arrival and departure point for all long-haul international flights. Located on the eastern tip of the main island, about 17 km from the central business district, it is served by MRT (Mass Rapid Transit) with a direct train to the city in roughly 30 minutes. Changi is a destination in its own right — with its famous Jewel complex, indoor waterfall, and extensive dining.
When booking flights to Singapore, you'll always be looking at SIN as your destination airport.
US departure cities for Singapore flights
Singapore Airlines operates one of the world's longest nonstop flights — the Singapore–New York route (SQ 22/23) via Newark (EWR), clocking in at roughly 18–19 hours. A Singapore–Los Angeles nonstop via Singapore Airlines also operates. For most US cities, however, a single connecting flight via an Asian hub is the norm:
| US Departure | Nonstop Available? | Common One-Stop Hubs | Total Travel Time |
|---|---|---|---|
| San Francisco (SFO) | Yes — Singapore Airlines (SQ) | Direct, or via Tokyo/Hong Kong | ~17–18 hrs nonstop |
| Los Angeles (LAX) | Yes — Singapore Airlines (SQ) | Direct, or via Tokyo/Seoul | ~17–18 hrs nonstop |
| New York (EWR) | Yes — Singapore Airlines (SQ) | Direct (~19 hrs) or via Hong Kong | ~18–19 hrs nonstop |
| Chicago (ORD) | No | Tokyo (NRT), Seoul (ICN), Hong Kong (HKG) | ~22–26 hrs |
| Dallas (DFW) | No | Tokyo (NRT), Seoul (ICN), Doha (DOH) | ~22–26 hrs |
The San Francisco to Singapore and Los Angeles to Singapore routes benefit from Singapore Airlines' direct service, which is premium in service quality. However, routing via other Asian carriers on a one-stop itinerary can sometimes undercut the nonstop fare considerably.
Best months for cheap flights to Singapore
Singapore sits just 1° north of the equator, so seasons are defined by rain patterns rather than temperature. Airfare seasonality is driven more by US and global travel calendars than local weather:
- Low season (best fares): February through early April and September through October. These quieter periods often yield fares in the $750–$900 range from the West Coast.
- Shoulder season: May–June and November. Good mix of value and manageable crowds. Singapore's F1 Grand Prix (usually September) can spike hotel prices but may not materially affect airfares.
- Peak season (highest fares): July–August (summer school holidays) and December through early January. Round-trip fares from the West Coast can exceed $1,100–$1,400 in peak periods.
Unlike some Asian destinations, Singapore is genuinely worth visiting year-round — the city is air-conditioned everywhere, and rain showers are brief. Read our full guide on when to book flights for the cheapest fare for booking lead-time strategy that maximizes savings.
Illustrative round-trip fare ranges from the US
Fares to Singapore reflect its long-haul distance and strong demand from business travelers. These figures are rough estimates — your agent will confirm current pricing:
| Departure City | Economy Low Season | Economy Peak Season | Business Class |
|---|---|---|---|
| San Francisco (SFO) | from around $760 | from around $1,100 | from around $3,200 |
| Los Angeles (LAX) | from around $780 | from around $1,120 | from around $3,200 |
| New York (EWR/JFK) | from around $850 | from around $1,200 | from around $3,500 |
| Chicago (ORD) | from around $870 | from around $1,220 | from around $3,600 |
Business class to Singapore can represent exceptional value on ultra-long-haul segments — on an 18-hour flight, the lie-flat seat is qualitatively different from economy. Call us to compare the full range of cabin options available.
Nonstop vs. one-stop flights to Singapore
Singapore Airlines' nonstop from SFO or LAX is roughly 17–18 hours. That is a very long time in economy — one of the longest flights in the world. For travelers prioritizing rest and minimal disruption, the nonstop is hard to beat. However, a one-stop routing via Seoul, Tokyo, or Hong Kong might be $150–$300 cheaper and only adds 2–4 hours to total travel time, which some travelers find acceptable. The calculus depends on your budget and tolerance for travel fatigue.
Tips to find cheaper Singapore flights
- Compare nonstop vs. one-stop pricing carefully. The gap between the two varies significantly by season and booking window.
- Look at Asian carrier one-stop options. Carriers like ANA, JAL, Korean Air, and Cathay Pacific frequently offer competitive fares via their hubs.
- Book 4–6 months ahead for peak travel. Summer and December demand means seats disappear early.
- Consider premium economy seriously. On a 17-18 hour flight, premium economy on Singapore Airlines or Cathay Pacific is among the best in the industry and costs far less than business class.
- Travel mid-week. Tuesday and Wednesday departures are consistently cheaper than weekend departures on transpacific routes.
