We’re seeing sub-$400 fares from San Francisco (SFO) to several destinations in Asia. Flights to Kuala Lumpur (KUL), Manila (MNL), Ho Chi Minh City (SGN), Bangkok (BKK) and Singapore (SIN) are all on sale. There may be other cities as well. These fares are on China Eastern, a mainline Chinese airline where service can be subpar at times. However, China Eastern is a Sky Team member, so you may be able to earn miles (50% with Flying Blue) with these flights. Flights are available from September through November and all require a connection in Shanghai.Airline: China EasternCost: $373+ round-tripDates: September 2016 - November 206Booking 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 Manila (MNL) for $373 round-trip in September:San Francisco (SFO) to Manila (MNL) for $373 round-trip.San Francisco (SFO) to Singapore (SIN) for $387 round-trip in September:San Francisco (SFO) to Singapore (SIN) for $387 round-trip.San Francisco (SFO) to Ho Chi Minh City (SGN) for $383 round-trip in September:San Francisco (SFO) to Ho Chi Minh City (SGN) for $383 round-trip.San Francisco (SFO) to Bangkok (BKK) for $384 round-trip in September:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
