We found availability from Los Angeles (LAX), San Fransisco (SFO), Chicago (ORD) and Newark (EWR) starting at $600 round-trip. But what’s more exciting is that Singapore’s inaugural nonstop flight from San Fransisco (SFO) to Singapore (SIN) on its A350 is also on sale (departing October 23). United just started service between the two cities on its 787 Dreamliner, which TPG Editor-in-Chief Zach Honig reviewed on its inaugural flight. Now that Singapore is adding nonstop service of its own, competition to the Southeast Asian metropolis is increasing.You can book a combination of United, ANA, Air China and Singapore Airlines flights on this deal. Availability is most days from September through March, with the Christmas holiday period being blacked out. The nonstop deal is only available from SFO, and the other origin cities each have one stop.Airline: United, Singapore, Air China and ANARoute: US cities to Singapore (SIN)Cost: $600+ round-trip in economyDates: September 2016 through March 2017Fare Class: K, LMiles Earned: At least 16,888 elite-qualifying milesBooking Link: OrbitzPay With: American Express Premier Rewards Gold, Citi Prestige or Chase Sapphire PreferredHere are some examples of what you can book:San Francisco (SFO) to Singapore (SIN) for $648 round-trip on Singapore (the inaugural flight):San Francisco (SFO) to Singapore (SIN) for $648 round-trip on Singapore (the inaugural flight).San Francisco (SFO) to Singapore (SIN) for $648 round-trip on United during Thanksgiving:San Francisco (SFO) to Singapore (SIN) for $648 round-trip on United during Thanksgiving.Los Angeles (LAX) to Singapore (SIN) for $616 round-trip on United and ANA in October:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
