We recommend you use Google Flights to find dates to fly, then book through an online travel agency, such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using The Platinum Card® from American Express, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.Several carriers are offering cheap fares on flights from a number of US cities to some of Southeast Asia’s most popular destinations. Score a round-trip ticket from Los Angeles (LAX) to Ho Chi Minh City for as little as $447 on Air China. However, there are other deals to be had to cities such as Singapore (SIN), Kuala Lumpur (KUL), Manila (MNL) and Hong Kong (HKG). These discounted fares are generally available from November 2017 through March 2018, but exact availability will depend on your origin and destination. We recommend doing your research through Google Flights and then booking either directly through the airlines themselves or with an OTA such as Expedia or Orbitz.Airlines: Air China, ANA, Asiana, UnitedRoutes: LAX/EWR/SFO/ORD to SIN/HKG/SGN/KUL/MNLCost: $447+ round-trip in economyDates: November 2017 - March 2018Booking Link: Orbitz or ExpediaPay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige Card (5x on airfare) or Chase Sapphire Preferred Card (2x on travel)Here are a few examples of what you can book:Los Angeles (LAX) to Ho Chi Minh City (SGN) for $447 round-trip on Air China:Newark (EWR) to Singapore (SIN) for $468 round-trip on United:Newark (EWR) to Kuala Lumpur (KUL) for $474 round-trip on ANA/United:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
