Japan Airlines is running a great deal for roundtrip Economy Class flights from Singapore to the west coast of the USA.
Singapore to San Francisco and Los Angeles from S$694
Travellers can browse air fares easily through the map/calendar view on Google Flights, in the months of July and August 2025. Replicating the search on jal.co.jp. The lowest fare available through the airline’s website is S$721.50 (scroll down to lower this further).
All 4 flights to/from San Francisco are operated by Japan Airlines. However, take note that American Airlines is operating the long flights between Tokyo and Los Angeles. I think it’s no secret that Japan Airlines is far superior, in any cabin class.
Be sure to explore various flight departure times, aircraft types and layover durations to see what suits you best.
Travellers can find even cheaper fares from S$694 at reputable online travel agencies (OTAs) like Trip.com and Agoda.
Add a stopover and open jaw for a little more
Travellers can add a longer stopover in Tokyo and an open jaw itinerary for just S$23 more.
For example, with this multi city booking, you can spend a few days in Tokyo before flying to San Francisco. You can then make your way to Los Angeles on your own (I recommend a scenic road trip), before flying home from LAX (add another stopover in Tokyo on your way back if you want!).
